Choose the CORRECT option for the sentence written in error below:

Economics have always been my favourite subject since class 9 in school.

((a))
Economics has always been my favourite subject since class 9 in school.
((b))
Economics have always being my favourite subject since class 9 in school.
((c))
Economics have been always my favourite subject since class 9 in school.
((d))
Economics are always been my favourite subjects since class 9 in school.

Show Answer

Answer: ((a))

Economics has always been my favourite subject since class 9 in school.

The correct answer is 'Economics has always been my favourite subject since class 9 in school'.

Key Points

In the given sentence usage of 'have' is incorrect.
'Economics' is used with a singular verb when it is referring to a subject that deals with the production, distribution, and consumption of goods and services and with the theory and management of economies or economic systems.
Example: Economics provides the foundation for all other cultural endeavors.
It functions as a plural noun when it is related to financial aspects.
Example: The economics of the project are very doubtful.
'Has' is used with the third person singular.
Example: He has a great idea.
'Have' is used with the first and second person singular present and plural tenses and the third person plural present tense.
Example: They also have a wonderful gift shop.
Therefore in the given sentence 'have' should be replaced by 'has' because economics is singular.
Hence, option 1 is the correct answer.

The correct sentence is: 'Economics has always been my favourite subject since class 9 in school'.

Additional Information

Many 'indefinite pronouns' look like they should be plural but refer to only a singular subject and therefore require a singular verb form.
Example: Each, everyone, nobody, nothing.

Hinglish

दिए गए वाक्य में 'have' शब्द का प्रयोग गलत है।
'Economics' का प्रयोग singular verb के साथ किया जाता है जब यह किसी ऐसे विषय का जिक्र करता है जो वस्तुओं और सेवाओं के उत्पादन, वितरण और खपत से संबंधित है और अर्थव्यवस्थाओं या आर्थिक प्रणालियों के सिद्धांत और प्रबंधन से संबंधित है।
उदाहरण: Economics provides the foundation for all other cultural endeavors.
यह वित्तीय पहलुओं से संबंधित होने पर plural noun के रूप में कार्य करता है।
उदाहरण: The economics of the project are very doubtful.
Third person singular के साथ 'Has' का प्रयोग किया जाता है।
उदाहरण: He has a great idea.
'Have' का प्रयोग first और second person singular वर्तमान और plural tense और third person plural वर्तमान काल के साथ किया जाता है।
उदाहरण: They also have a wonderful gift shop.
इसलिए दिए गए वाक्य में 'have' को 'has' से बदल देना चाहिए क्योंकि economics singular है।
अत: विकल्प 1 सही उत्तर है।
कई 'indefinite pronouns' ऐसे दिखते हैं जैसे वे plural होने चाहिए लेकिन केवल singular subject को संदर्भित करते हैं और इसलिए एकवचन क्रिया रूप की आवश्यकता होती है।
उदाहरण: Each, everyone, nobody, nothing.

सही वाक्य है: 'Economics has always been my favourite subject since class 9 in school'.

Fill in the blank with a suitable preposition in the given sentence:

The children are playing _______ the garden.

((a))
into
((b))
in
((c))
at
((d))
over

Show Answer

Answer: ((b))

The correct answer is 'in'.

Key Points

We use 'in' to talk about where something is in relation to a larger area around it.
Example: She’s in the garden.
We use 'into' to talk about the movement of something, usually with a verb that expresses movement (e.g. go, come). It shows where something is or was going.
Example: She’s gone into the house.
Therefore in the given sentence, the most suitable preposition is 'in'.
Hence, option 2 is the correct answer.

The complete sentence is: The children are playing in the garden.

Additional Information

Let's learn about other given options:

'At' is a preposition. We use 'at' to refer to time or place. We also use it to refer to activities.
Example: I was up at 6 am this morning.
We use 'over' to talk about movement or position at a higher level than something else.
Example: A beautiful white bird flew over the lake.

Hinglish

हम 'in' का उपयोग इस बारे में बात करने के लिए करते हैं कि कोई चीज़ उसके आसपास के बड़े क्षेत्र के संबंध में कहाँ है।
उदाहरण: वह बगीचे में है।
हम किसी चीज की गति के बारे में बात करने के लिए 'into' का उपयोग करते हैं, आमतौर पर एक क्रिया के साथ जो गति को व्यक्त करती है (जैसे जाओ, आओ)। यह दिखाता है कि कुछ कहाँ है या जा रहा था।
उदाहरण: वह घर में गई है।
इसलिए दिए गए वाक्य में सबसे उपयुक्त preposition 'in' है।
अतः विकल्प 2 सही उत्तर है।
'At' एक preposition है। हम समय या स्थान के संदर्भ में 'at' का प्रयोग करते हैं। हम इसका उपयोग गतिविधियों को संदर्भित करने के लिए भी करते हैं।
उदाहरण: I was up at 6 am this morning.
हम किसी और चीज की तुलना में उच्च स्तर पर आंदोलन या स्थिति के बारे में बात करने के लिए 'over' उपयोग करते हैं
उदाहरण: A beautiful white bird flew over the lake.

पूरा वाक्य: The children are playing in the garden.

If the HCF of 306 and 657 = 9, then find the LCM.

((a))
23238
((b))
33228
((c))
22338
((d))
32328

Show Answer

Answer: ((c))

22338

Given:

Two numbers = 306 and 657

HCF = 9

Formula:

HCF × LCM = Product of two numbers

Calculation:

LCM × 9 = 306 × 657

LCM = (306 × 657)/9 = 22338

∴ LCM of 306 and 657 is 22338.

Which is CORRECT value of ΔH for isothermal expansion of a perfect gas ?

((a))
ΔH < 0
((b))
ΔH > 0
((c))
ΔH = W
((d))
ΔH = 0

Show Answer

Answer: ((c))

ΔH = W

The correct answer is ΔH = W.

Important Points

Isothermal expansion occurs when a substance expands in volume at a constant temperature.
Because the gas exerts energy in order to increase its volume, the work is negative-signed.
Only an ideal gas has a change in internal energy U of 0 during isothermal circumstances, therefore efficient work is completely turned into efficient heat flow.

Key Points

ΔH = W for isothermal expansion of a perfect gas.
Heat supplied to the system is used up entirely by the system is doing work on the environment.
During an isothermal expansion, the enthalpy and internal energy of an ideal gas stay constant.
isothermal expansion of an ideal gas in a cylinder fitted with a frictionless movable piston is a reversible process.

Which is one of the following is CORRECT for a galvanic cell?

((a))
Electric current is flowing from anode to cathode in external circuit
((b))
Electric current is flowing from cathode to anode in external circuit
((c))
Cell reaction is non-spontaneous
((d))
Anode has positive charge

Show Answer

Answer: ((b))

Electric current is flowing from cathode to anode in external circuit

The correct answer is Electric current is flowing from cathode to anode in the external circuit.

Key Points

A galvanic cell or voltaic cell is an electrochemical cell that converts the chemical energy of spontaneous redox reactions into electrical energy.
A galvanic cell is an electrochemical cell that generates electricity through chemical processes.

Important Points

The electric current in a galvanic cell is flowing from cathode to anode in the external circuit.
In a galvanic cell, the half-cell in which oxidation takes place is called the anode and it has a negative potential with respect to the solution.
The other half-cell in which reduction takes place is called the cathode and it has a positive potential with respect to the solution.
There is a potential difference between the two electrodes, and electrons flow from the negative electrode to the positive electrode as soon as the switch is turned on.
The flow of current is in the opposite direction as the flow of electrons.
The Gibbs energy of the spontaneous redox reaction is transformed into electrical work in a galvanic cell, which can be used to power a motor or other electrical devices such as a heater, fan, or geyser.

The correct answer is 'Drought'.

Key Points

'Drought' is a prolonged period of abnormally low rainfall, leading to a shortage of water. (सूखा)
Example: This year severe drought has ruined the crops.
Because of low rainfall crops are damaged.
Some synonyms of 'drought' are aridity, scarcity, dehydration, dessication etc.
Therefore, the most appropriate word for the given sentence is 'drought'.
Hence, option 4 is the correct answer.

Additional Information

'Draft' means a piece of writing, etc. which will probably be changed and improved; not the final version. (प्रारूप)
'Heat wave' is a prolonged period of abnormally hot weather. (गर्मी की लहर)
'Famine' is a situation in which there is not enough food for a great number of people, causing illness and death, or a particular period when this happens. (अकाल)

If a + b ∶ b + c ∶ c + a = 6 ∶ 7 ∶ 8 and a + b + c = 14, then the value of c is:

((a))
7
((b))
14
((c))
6
((d))
8

Show Answer

Answer: ((c))

Given:

⇒ a + b ∶ b + c ∶ c + a = 6 ∶ 7 ∶ 8

⇒ a + b + c = 14

Calculation:

Let (a + b), (b + c) and (c + a) be 6k, 7k and 8k respectively,

Then,

⇒ 6k + c = 14

⇒ 7k + a + 14

⇒ 8k + b = 14

Adding,

⇒ 21k + (a + b + c) = 42

⇒ 21k + 14 = 42

⇒ 21k = 28

⇒ k = 4/3

Then,

⇒ 6k + c = 14

⇒ c = 14 - 6 × 4/3

∴ c = 6

((a))
made from
((b))
makes of
((c))
full of
((d))
makes out of

Show Answer

Answer: ((a))

made from

The correct answer is 'made from'.

Key Points

We use 'made from' when we talk about how something is manufactured.
Example: The earliest canoes were made from tree trunks.
Therefore, in the given sentence 'made from' is the most appropriate phrase because it is telling us that limestone was used for constructing Mayan buildings.
Hence, option 1 is the correct answer.

The correct sentence is: Mayan buildings were typically made from limestone.

Additional InformationLet's learn about other given options:

We use 'makes of' when we talk about the basic material or qualities of something. It has a meaning similar to ‘composed of’.
Example: She wore a beautiful necklace made of silver.
We use 'makes out of' when we talk about something that has been changed or transformed from one thing into another.
Example: They were living in tents made out of old plastic sheets.
'Full of' means holding or containing as much as possible or a lot.
Example: When she looked at him her eyes were full of tears.

Hinglish

जब हम किसी चीज के निर्माण के बारे में बात करते हैं तो हम 'made from' का उपयोग करते हैं।
उदाहरण: The earliest canoes were made from tree trunks.
इसलिए दिए गए वाक्य में 'made from' सबसे उपयुक्त phrase है क्योंकि यह हमें बता रहा है कि चूना पत्थर का उपयोग माया भवनों के निर्माण के लिए किया गया था।
अत: विकल्प 1 सही उत्तर है।
जब हम मूल सामग्री या किसी चीज के गुणों के बारे में बात करते हैं तो हम 'make of' का उपयोग करते हैं। इसका एक अर्थ 'composed of' के समान है।
उदाहरण: She wore a beautiful necklace made of silver.
हम 'make out of' का उपयोग तब करते हैं जब हम किसी ऐसी चीज़ के बारे में बात करते हैं जिसे एक चीज़ से दूसरी चीज़ में बदल दिया गया है या बदल दिया गया है।
उदाहरण: They were living in tents made out of old plastic sheets.
'Full of' का अर्थ है जितना हो सके या बहुत कुछ रखना।
उदाहरण: When she looked at him her eyes were full of tears.

सही वाक्य है: Mayan buildings were typically made from limestone.

Choose the right tag to complete the given sentence:

Megha loves to dance, _______

((a))
doesn’t she?
((b))
will she?
((c))
does she?
((d))
isn’t it?

Show Answer

Answer: ((a))

doesn’t she?

The correct answer is 'doesn't she?'

Key Points

We can add question tags like isn't it?, can you? or didn't they? to a statement to make it into a question.
We often use question tags when we expect the listener to agree with our statement. In this case, when the statement is positive, we use a negative question tag.
Example: She's a doctor, isn't she?
If there is an auxiliary verb in the statement, we use it to form the question tag.
Example: James is working on that, isn't he?
Sometimes there is no auxiliary verb already in the statement:
When the verb in the statement is present simple or past simple and is positive we use don't, doesn't or didn't:
Example: Jenni eats cheese, doesn't she?
Therefore, in the given sentence 'doesn't she' is the most appropriate question tag because here there is no auxiliary verb and the verb is in simple present tense and is positive.
Hence, option 1 is the correct answer.

The correct sentence is: Megha loves to dance, doesn't she?

Additional Information

If the statement is negative, we use a positive question tag.
Example: The trains are never on time**, are they?**
If the main verb or auxiliary verb in the statement is am, the positive question tag is 'am I?' but the negative question tag is usually 'aren't I'?
Example: I'm never on time, am I?

I'm going to get an email with the details, aren't I?

Hinglish

हम question tag जोड़ सकते हैं जैसे isn't it?,can you? या didn't they? एक बयान के लिए इसे एक प्रश्न में बनाने के लिए।
जब हम श्रोता से हमारे कथन से सहमत होने की अपेक्षा करते हैं तो हम अक्सर question tag का उपयोग करते हैं। इस मामले में, जब कथन सकारात्मक होता है, तो हम नकारात्मक question tag का उपयोग करते हैं।
उदाहरण: She's a doctor, isn't she?
यदि कथन में कोई auxiliary verb है, तो हम उसका उपयोग question tag बनाने के लिए करते हैं।
उदाहरण: James is working on that, isn't he?
कभी-कभी कथन में पहले से कोई auxiliary verb नहीं होती है:
जब कथन में verb simple present या simple past मौजूद होती है और सकारात्मक होती है तो हम उपयोग don't, doesn't, didn't करते हैं:
उदाहरण: Jenni eats cheese, doesn't she?
इसलिए, दिए गए वाक्य में 'doesn't she' सबसे उपयुक्त question tag है क्योंकि यहाँ verb simple present tense में है और सकारात्मक है।
अत: विकल्प 1 सही उत्तर है।
यदि कथन नकारात्मक है, तो हम सकारात्मक question tag का उपयोग करते हैं।
उदाहरण: The trains are never on time, are they?
यदि कथन में main verb या auxiliary verb 'am' है, तो सकारात्मक qusetion tag 'am I?' है लेकिन नकारात्मक qusetion tag आमतौर पर 'aren't I?' है?
उदाहरण: I'm never on time, am I?

I'm going to get an email with the details, aren't I?

सही वाक्य है: Megha loves to dance, doesn't she?

Choose the appropriate idiomatic expression for the given sentence:

After not speaking to each other for a year, the two friends decided _______.

((a))
to smell a rat
((b))
to call it a day
((c))
to call it null and void
((d))
to bury the hatchet

Show Answer

Answer: ((d))

to bury the hatchet

The correct answer is 'to bury the hatchet'.

Key Points

'Bury the hatchet' means end a quarrel or conflict and become friendly. (झगड़ा या संघर्ष समाप्त करें और मैत्रीपूर्ण बनें।)
Example: Tom and I buried the hatchet and we are good friends now.
Therefore in the given sentence, the most appropriate idiomatic expression is 'to bury the hatchet' because it is talking about two people becoming friends after ending a conflict.
Hence, option 4 is the correct answer.

The correct sentence is: After not speaking to each other for a year, the two friends decided to bury the hatchet.

Additional InformationLet's learn about other given options:

'To smell a rat' means to recognize that something is not as it appears to be or that something dishonest is happening. (यह पहचानने के लिए कि कुछ ऐसा नहीं है जैसा प्रतीत होता है या कुछ बेईमानी हो रही है)
Example: He's been working late with her every night this week - I smell a rat!
'To call it a day' means to stop what you are doing because you do not want to do any more or think you have done enough. (आप जो कर रहे हैं उसे रोकने के लिए क्योंकि आप और अधिक नहीं करना चाहते हैं या सोचते हैं कि आपने पर्याप्त किया है)
Example: After 14 years living and working in this country, she thinks it's time to call it a day.
'To call it null and void' means having no legal force. (कोई कानूनी बल नहीं होना)
Example: The change in the law makes the previous agreement null and void.

The line which is passing through points (-1, 4) and (2, 6) is perpendicular to the line through the points (3, 7) and (x, 8). Find the value of x.

((a))
$\frac{7}{3}$
((b))
$\left|\frac{3}{7}\right|$
((c))
$\frac{2}{3}$
((d))
$\frac{7}{2}$

Show Answer

Answer: ((a))

$\frac{7}{3}$

Given:

One line : (-1,4) and (2,6)

Other line : (3,7) and (x,8)

Formula:

When two lines are perpendicular then product of their slope is -1.

Slope of line passing through (x1,y1) and (x2,y2) = (y2 - y1)/(x2 - x1)

Calculation:

Slope of line passing through (-1,4) and (2,6) = (6 - 4)/(2 - (-1)) = 2/3

Slope of line passing through (3,7) and (x,8) = (8 - 7)/(x - 3) = 1/(x - 3)

Then,

⇒ 2/3 × 1/(x - 3) = -1

⇒ 2 = -3x + 9

⇒ -3x = -7

∴ x = 7/3

Which of the following sentences is WRONG?

((a))
They have known me for a very long time.
((b))
They are known to many people.
((c))
They are knowing me for a very long time.
((d))
They know a lot of people.

Show Answer

Answer: ((c))

They are knowing me for a very long time.

The correct answer is 'They are knowing me for a very long time'.

Key Points

Verbs can be considered to be either action verbs or state verbs.
Action verbs are the verbs used to convey action.
Example: run, jump, dance, fight, etc.
State verbs, however, usually do not convey an action but they convey information about our ideas, thoughts, feelings and existence.
Example: think, feel, know, believe, be or have.
In general, we don't use present continuous with states, emotions, and general realities.
The following verbs are not normally used in the present continuous : like, love, hate, want, need, prefer, know, realize, suppose, mean, understand, believe, remember, belong, fit, contain, consist, seem.
This is because the continuous indicates that something is happening now (although it may have commenced in the past), and will probably cease at some stage in the future.
A state, as opposed to an action, has a more permanent character associated with it.
If you know something then, assuming what you know is correct, it is not likely that you will suddenly cease knowing.
Example: I know 15 digits of pi, because I memorized them in eighth grade, and will not forget them until my brain disintegrates.
Therefore, option 3 is the incorrect statement.
Hence, option 3 is the **correct answer.**

Additional Information

Tense	Simple tense	Continuous tense	Perfect tense	Perfect continuous
Present	v1+s/es	is/am/are+v1+ing	has/have+v3	has/have been+v1+ing
Past	v2	was/were+v1+ing	had+v3	had been+v1+ing
Future	will/shall+v1	will be+v1+ing	will have+v3	will+have been+v1+ing

Hinglish

Verbs को या तो action verb या state verb माना जा सकता है।
Action verb वे क्रियाएं हैं जिनका उपयोग action को व्यक्त करने के लिए किया जाता है।
उदाहरण: run, jump, dance, fight, etc.
हालाँकि, State verbs आमतौर पर किसी क्रिया को व्यक्त नहीं करती हैं, लेकिन वे हमारे विचारों, विचारों, भावनाओं और अस्तित्व के बारे में जानकारी देती हैं।
उदाहरण: think, feel, know, believe, be or have.
सामान्य तौर पर, हम states, emotions और general realities के साथ present continuous का उपयोग नहीं करते हैं।
निम्नलिखित क्रियाओं का उपयोग सामान्य रूप से present continuous में नहीं किया जाता है: like, love, hate, want, need, prefer, know, realize, suppose, mean, understand, believe, remember, belong, fit, contain, consist, seem.
ऐसा इसलिए है क्योंकि continuous इंगित करता है कि कुछ अभी हो रहा है (हालांकि यह अतीत में शुरू हो सकता है), और शायद भविष्य में किसी चरण में समाप्त हो जाएगा।
एक state, एक action के विपरीत, इससे जुड़ा एक अधिक स्थायी चरित्र होता है।
यदि आप कुछ जानते हैं, तो यह मानकर कि आप जो जानते हैं वह सही है, यह संभावना नहीं है कि आप अचानक जानना बंद कर देंगे।
उदाहरण: I know 15 digits of pi, because I memorized them in eighth grade, and will not forget them until my brain disintegrates.
अतः विकल्प 3 गलत कथन है।
अत: विकल्प 3 सही उत्तर है।

Identify the grammatical error in the below sentence.

We don't have to go to the party, don’t we? We can stay at home.

((a))
don't we
((b))
have to go
((c))
to the party
((d))
can stay

Show Answer

Answer: ((a))

don't we

The correct answer is 'don't we?'

Key Points

The erroneous part in the given sentence is 'don't we?'.
We can add question tags like isn't it?, can you? or didn't they? to a statement to make it into a question.
We often use question tags when we expect the listener to agree with our statement.
If the statement is negative, we use a positive question tag.
Example: He isn't here, is he?
If there is an auxiliary verb in the statement, we use it to form the question tag.
Example: I don't need to finish this today, do I?
Therefore, from the above explanation, it is clear that 'don't we?' should be replaced with 'do we?'.
This is because the statement is negative i.e, we don't have to go to the party, so we should have a positive question tag.
Hence, option 1 is the correct answer.

The correct sentence is: We don't have to go to the party, do we? We can stay at home.

Additional Information

When the statement is positive, we use a negative question tag.
Example: She's a doctor, isn't she?
When the verb in the statement is present simple or past simple and is positive, we use don't, doesn't or didn't.
Example: Jenni eats cheese, doesn't she?

Hinglish

हम question tag जोड़ सकते हैं जैसे isn't it?,can you? या didn't they? एक बयान के लिए इसे एक प्रश्न में बनाने के लिए।
जब हम श्रोता से हमारे कथन से सहमत होने की अपेक्षा करते हैं तो हम अक्सर question tag का उपयोग करते हैं। इस मामले में, जब कथन सकारात्मक होता है, तो हम नकारात्मक question tag का उपयोग करते हैं।
उदाहरण: She's a doctor, isn't she?
यदि कथन में कोई auxiliary verb है, तो हम उसका उपयोग question tag बनाने के लिए करते हैं।
उदाहरण: I don't need to finish this today, do I?
कभी-कभी कथन में पहले से कोई auxiliary verb नहीं होती है:
जब कथन में verb simple present या simple past मौजूद होती है और सकारात्मक होती है तो हम उपयोग don't, doesn't, didn't करते हैं:
उदाहरण: Jenni eats cheese, doesn't she?
यदि कथन नकारात्मक है, तो हम सकारात्मक question tag का उपयोग करते हैं।
उदाहरण: He isn't here, is he?
इसलिए, उपरोक्त स्पष्टीकरण से, यह स्पष्ट है कि 'don't we?' 'do we?' से प्रतिस्थापित किया जाना चाहिए।
ऐसा इसलिए है क्योंकि statement negative है यानी we don't have to go to the party, इसलिए हमारे पास positive question tag होना चाहिए।
अत: विकल्प 1 सही उत्तर है।

सही वाक्य है: We don't have to go to the party, do we? We can stay at home.

((d))
6x – 1

Show Answer

Answer: ((a))

6x + 1

Given:

2f(x) + 3f(-x) = 5 - 6x

Calculation:

Replace x by -x then,

3f(x) + 2f(-x) = 5 + 6x

Solving,

⇒ 4f(x) + 6f(-x) = 10 - 12x ----(1)

⇒ 9f(x) + 6f(-x) = 15 + 18x ----(2)

Subtracting (1) from (2),

⇒ 5f(x) = 5 + 30x

⇒ f(x) = 1 + 6x

∴ f(x) = 6x + 1

Choose the right tag to complete the given sentence:

You woke up very early this morning, _______

((a))
don’t you?
((b))
have you?
((c))
did you?
((d))
didn’t you?

Show Answer

Answer: ((d))

didn’t you?

The correct answer is 'didn't you?'

Key Points

We can add question tags like isn't it?, can you? or didn't they? to a statement to make it into a question.
We often use question tags when we expect the listener to agree with our statement. In this case, when the statement is positive, we use a negative question tag.
Example: She's a doctor, isn't she?
If there is an auxiliary verb in the statement, we use it to form the question tag.
Example: James is working on that, isn't he?
Sometimes there is no auxiliary verb already in the statement:
When the verb in the statement is present simple or past simple and is positive we use don't, doesn't or didn't:
Example: Jenni eats cheese, doesn't she?
Therefore, in the given sentence 'didn't you?' is the most appropriate question tag because here there is no auxiliary verb and the verb is in simple past tense and is positive.
Hence, option 4 is the correct answer.

The correct sentence is: You woke up early this morning, didn't you?

Additional Information

If the statement is negative, we use a positive question tag.
Example: The trains are never on time, are they?
If the main verb or auxiliary verb in the statement is am, the positive question tag is 'am I?' but the negative question tag is usually 'aren't I'?
Example: I'm never on time, am I?

I'm going to get an email with the details, aren't I?

Hinglish

हम question tag जोड़ सकते हैं जैसे isn't it?,can you? या didn't they? एक बयान के लिए इसे एक प्रश्न में बनाने के लिए।
जब हम श्रोता से हमारे कथन से सहमत होने की अपेक्षा करते हैं तो हम अक्सर question tag का उपयोग करते हैं। इस मामले में, जब कथन सकारात्मक होता है, तो हम नकारात्मक question tag का उपयोग करते हैं।
उदाहरण: She's a doctor, isn't she?
यदि कथन में कोई auxiliary verb है, तो हम उसका उपयोग question tag बनाने के लिए करते हैं।
उदाहरण: James is working on that, isn't he?
कभी-कभी कथन में पहले से कोई auxiliary verb नहीं होती है:
जब कथन में verb simple present या simple past मौजूद होती है और सकारात्मक होती है तो हम उपयोग don't, doesn't, didn't करते हैं:
उदाहरण: Jenni eats cheese, doesn't she?
इसलिए, दिए गए वाक्य में 'didn't you' सबसे उपयुक्त question tag है क्योंकि यहाँ verb simple past tense में है और सकारात्मक है।
अत: विकल्प 4 सही उत्तर है।
यदि कथन नकारात्मक है, तो हम सकारात्मक question tag का उपयोग करते हैं।
उदाहरण: The trains are never on time, are they?
यदि कथन में main verb या auxiliary verb 'am' है, तो सकारात्मक qusetion tag 'am I?' है लेकिन नकारात्मक qusetion tag आमतौर पर 'aren't I?' है?
उदाहरण: I'm never on time, am I?

I'm going to get an email with the details, aren't I?

सही वाक्य है: You woke up early this morning, didn't you?

People who _______ alone _______ more prone to mental disorders and the number of people living alone _______ steadily.

((a))
have been living, have been, have been increasing
((b))
are living, is, increased
((c))
lived, has, have increased
((d))
live, are, has been increasing

Show Answer

Answer: ((d))

live, are, has been increasing

The correct answer is 'live, are, has been increasing'.

Key Points

The given sentence is in the present tense.
In the first blank 'live' is the most appropriate form of the verb because 'people' is the plural subject.
In the second blank 'are' should be used because 'people' is the plural subject.
'Is' is used for a singular noun. Therefore, Option 2 is eliminated.
Option 3 is eliminated because in the second blank 'people' being plural form will use either 'have' or 'are' as verbs and not 'has'. This is because 'has' is used with singular subjects.
In the third blank 'has been increasing' is the correct structure of the present perfect continuous tense.
The phrase 'a number of___' is treated as plural. When used a subject of a sentence or clause, the verb must also be plural.
The phrase 'the number of__' is treated as singular even when the noun that fills in the blank is plural. When used a subject of a sentence or clause, the verb must be singular.
Therefore, option 4 is the correct answer.

The correct sentence is: People who live alone are more prone to mental disorders and the number of people living alone has been increasing steadily.

Additional Information

Tense	Simple tense	Continuous tense	Perfect tense	Perfect continuous
Present	v1+s/es	is/am/are+v1+ing	has/have+v3	has/have been+v1+ing
Past	v2	was/were+v1+ing	had+v3	had been+v1+ing
Future	will/shall+v1	will be+v1+ing	will have+v3	will+have been+v1+ing

Hinglish

दिया गया वाक्य वर्तमान काल में है।
पहले रिक्त स्थान में 'live' क्रिया का सबसे उपयुक्त रूप है क्योंकि 'people' बहुवचन subject है।
दूसरे रिक्त स्थान में 'are' का प्रयोग किया जाना चाहिए क्योंकि 'people' बहुवचन subject है।
'Is' एकवचन संज्ञा के लिए प्रयोग किया जाता है। इसलिए, विकल्प 2 को हटा दिया जाता है।
विकल्प 3 समाप्त हो गया है क्योंकि 'people' बहुवचन रूप होने के कारण second blank में या तो 'are' या 'have' का प्रयोग क्रिया के रूप में करेंगे, न कि 'has'। ऐसा इसलिए है क्योंकि एकवचन subjects के साथ 'has' का प्रयोग किया जाता है।
तीसरे रिक्त स्थान में 'has been increasing' present perfect continuous tense की सही संरचना है।
वाक्यांश ''a number of___'' को बहुवचन के रूप में माना जाता है। जब किसी वाक्य या clause के subject का उपयोग किया जाता है, तो क्रिया भी बहुवचन होनी चाहिए।
वाक्यांश ''the number of__'' को एकवचन के रूप में माना जाता है, भले ही रिक्त स्थान को भरने वाली संज्ञा बहुवचन हो। जब किसी वाक्य या clause के subject का उपयोग किया जाता है, तो क्रिया एकवचन होनी चाहिए।
अतः विकल्प 4 सही उत्तर है।

सही वाक्य है: People who live alone are more prone to mental disorders and the number of people living alone has been increasing steadily.

What is the capacitance of a parallel plate capacitor having 10 cm ×10 square plates separated by a distance of 1 mm?

((a))
8.85 × 10^-10 F
((b))
8.85 × 10-9 F
((c))
8.85 × 10-12 F
((d))
8.85 × 10-11 F

Show Answer

Answer: ((d))

8.85 × 10-11 F

The correct answer is 8.85 × 10-11 F.

The capacitance of a parallel plate capacitor is:

$C={∈_0 \times A \over d}$

∈₀ is Absolute permittivity of free space =8.85x10^-12Fm^-1.

A is Area = 10cm ×10cm.

d is distance= 1 mm.

$C={{{{8.85\times10^{-12}Fm^{-1}}} \times {10\times10^{-2} ×10\times10^{-2} }}\over {1\times 10^{-3}m}}$

$C={{{{8.85\times10^{-12}Fm^{-1}}} \times {10^{-2} }}\over {1\times 10^{-3}m}}$

$C={8.85\times10^{-12}F}\times 10$

$C={8.85\times10^{-11}} F$

The capacitance of a parallel plate capacitor is 8.85 × 10-¹¹ F.

If sinθ = cosθ, find the value of 'θ'?

((a))
30°
((b))
60°
((c))
45°
((d))
90°

Show Answer

Answer: ((c))

45°

Given:

sinθ = cosθ

Calculation:

sin θ = sin (90 - θ)

Taking inverse both sides,

⇒ θ = 90 - θ

⇒ 2θ = 90°

∴ θ = 45°

Which one of the following quantity determines the direction of flow of heat when two bodies at different temperatures are brought in contact?

((a))
Volume of the bodies
((b))
Temperature of the bodies
((c))
Mass of the bodies
((d))
Material of the bodies

Show Answer

Answer: ((b))

Temperature of the bodies

The correct answer is Temperature of the bodies.

Key Points

Heat transfers from the body at a higher temperature to the body at a lower temperature when two bodies at different temperatures are kept in touch.
It is governed by the second law of thermodynamics.
The temperature of the bodies determines the direction of the flow of heat when two bodies at different temperatures are brought in contact.
As a result, the direction of heat movement is determined by the temperature.
The objects will exchange thermal energy until they reach thermal equilibrium, or when their temperatures are the same.
Temperature is measured using a thermometer.
SI unit of temperature is Kelvin.
In most parts of the world, the Celsius scale (°C) is used to measure temperature.

Choose the appropriate pronoun for the given sentence:

The children finished _______ homework; _______ are now playing.

((a))
our, they
((b))
her, you
((c))
their, they
((d))
your, you

Show Answer

Answer: ((c))

their, they

The correct answer is 'their, they'.

Key Points

'Their' is the possessive form of 'they', so it has to do with what belongs to, relates to, or is made or done by certain people, animals, or things.
Example: It's their house.
'They' is used to refer to the subject of a clause. In other words, it usually represents the ‘doers’ of the action described by the verb, and usually refers back to two or more people or things that were mentioned earlier.
Example: Jan and Tom aren’t coming. They said they couldn’t make it.
In the given sentence, 'their' will be used in the first blank because it indicates that the homework belongs to the students.
In the second blank, 'they' will be used because it indicates the subject (students) mentioned earlier.
Hence, option 3 is the correct answer.

The complete sentence is: The children finished their homework; they are now playing.

Additional Information

'Them' is used to refer to the object of a clause.
Example: I’ve bought some apples. I’ll put them on the table.
When we use 'there', it typically refers to the place where the listener or another person is, and we see the position of people and things from the listener’s or another person’s point of view.
Example: We went to Paris and stayed there ten days.

Hinglish

'Their' 'they' का possessive form है, इसलिए इसका अर्थ उनका है।
उदाहरण: It's their house.
'They' एक clause के subject को संदर्भित करने के लिए प्रयोग किया जाता है। दूसरे शब्दों में, यह आमतौर पर क्रिया द्वारा वर्णित क्रिया के 'कर्ता' का प्रतिनिधित्व करता है, और आमतौर पर दो या दो से अधिक लोगों या चीजों को संदर्भित करता है जिनका उल्लेख पहले किया गया था।
उदाहरण: Jan and Tom aren’t coming. They said they couldn’t make it.
दिए गए वाक्य में, पहले रिक्त स्थान में 'theirs' का प्रयोग किया जाएगा क्योंकि यह इंगित करता है कि गृहकार्य छात्रों का है।
दूसरे रिक्त स्थान में, 'they' का प्रयोग किया जाएगा क्योंकि यह पहले बताए गए विषय (छात्रों) को इंगित करता है।
अत: विकल्प 3 सही उत्तर है।
'Them' किसी clause की object को संदर्भित करने के लिए प्रयोग किया जाता है।
उदाहरण: I’ve bought some apples. I’ll put them on the table.
जब हम 'there' का उपयोग करते हैं, तो यह आम तौर पर उस स्थान को संदर्भित करता है जहां श्रोता या कोई अन्य व्यक्ति होता है, और हम श्रोता या किसी अन्य व्यक्ति के दृष्टिकोण से लोगों और चीजों की स्थिति देखते हैं।
उदाहरण: We went to Paris and stayed there ten days.

पूरा वाक्य है: The children finished their homework; they are now playing.

Fill in the blanks with the appropriate article in the given sentence:

_______ beggar was _______ honest man and returned _______ bag of money he found near the dustbin.

((a))
A, a, the
((b))
A, the, a
((c))
An, the, a
((d))
The, an, the

Show Answer

Answer: ((d))

The, an, the

The correct answer is 'The, an, the'.

Key Points

'The' is used to refer to specific or particular nouns.
'a/an' is used to modify non-specific or non-particular nouns.
We call 'the' the definite article and 'a/an' the indefinite article.
Example: Let's read the book. (This means a specific book.)

Let's read a book. (This means any book rather than a specific book.)

In the given sentence, article 'the' will be most appropriate because it is referring to a particular beggar.
In the second blank, 'an' will come because if the noun is modified by an adjective, the choice between 'a' and 'an' depends on the initial sound of the adjective that immediately follows the article. Here 'honest' starts with a vowel.
In the third blank, article 'the' will come because it is referring to the specific bag of money he found near the dustbin.
Hence, option 4 is the correct answer.

The correct sentence is: The beggar was an honest man and returned the bag of money he found near the dustbin.

Additional Information

The indefinite articles are used to indicate membership in a group.
Example: I am a teacher. (I am a member of a large group known as teachers.)
The can be used with noncount nouns, or the article can be omitted entirely.
Example: I love to sail over the water. (some specific body of water) or I love to sail over water (any water).

Hinglish

'The' का प्रयोग विशिष्ट या विशेष संज्ञाओं को संदर्भित करने के लिए किया जाता है।
'a/an' का उपयोग गैर-विशिष्ट या गैर-विशिष्ट संज्ञाओं को संशोधित करने के लिए किया जाता है।
हम 'The' को definite article और 'a/an' को indefinite article कहते हैं।
उदाहरण: Let's read the book. (This means a specific book.)

Let's read a book. (This means any book rather than a specific book.)

दिए गए वाक्य में article 'the' सर्वाधिक उपयुक्त होगा क्योंकि यह एक विशेष भिखारी की बात कर रहा है।
दूसरे रिक्त स्थान में, 'a' आएगा क्योंकि यदि संज्ञा को विशेषण द्वारा संशोधित किया जाता है, तो 'a' और 'a' के बीच का चुनाव विशेषण की प्रारंभिक ध्वनि पर निर्भर करता है जो artcle के तुरंत बाद आता है। यहाँ 'honest' एक vowel से शुरू होता है।
तीसरे खाली में, article 'the' आएगा क्योंकि यह कूड़ेदान के पास मिले पैसे के विशिष्ट बैग का जिक्र कर रहा है।
अतः विकल्प 4 सही उत्तर है।
Indefinite article का उपयोग किसी समूह में सदस्यता को इंगित करने के लिए किया जाता है।
उदाहरण: I am a teacher. (मैं शिक्षकों के नाम से जाने जाने वाले एक बड़े समूह का सदस्य हूं।)
Non-countable nouns के साथ 'the' प्रयोग किया जा सकता है, या article को पूरी तरह से छोड़ा जा सकता है।
उदाहरण: I love to sail over the water. (some specific body of water) or I love to sail over water (any water)

सही वाक्य है: The beggar was an honest man and returned the bag of money he found near the dustbin.

According to Gauss's law, the electric flux through a closed surface is given by:

((a))
$\frac{q}{\epsilon_0}$
((b))
q ϵ₀
((c))
$\frac{q^2}{\epsilon_0}$
((d))
$\frac{\epsilon_0}{q}$

Show Answer

Answer: ((a))

$\frac{q}{\epsilon_0}$

The correct answer is $q \over \varepsilon_0$

Key Points

The total electric flux out of a closed surface is equal to the charge enclosed divided by the permittivity, according to Gauss' law.
If no charge is encapsulated by the surface, the total electric flow through it is zero.
According to Gauss's law, the electric flux through a closed surface is given by $q \over \varepsilon_0$
$q \ is\ total \ charge\ enclosed\ within\ given \ Volume$
$\varepsilon_0 \ is\ electric\ constant$
Gauss' law applies to every closed surface, regardless of shape or size.
It's one of Maxwell's electromagnetic laws' four equations.
Carl Friedrich Gauss first proposed it in 1835, and it connects the electric fields at points on a closed surface to the net charge encompassed by that surface.

In AP, sum of the three numbers is 6 and its product is 6. Find the numbers.

((a))
4, 5 and 8
((b))
1, 2 and 3
((c))
1, 6 and 8
((d))
1, 2 and 6

Show Answer

Answer: ((b))

1, 2 and 3

Given:

Sum of three numbers = 6

Product of numbers = 6

Calculation:

Let three numbers in AP be a, (a + d) and (a + 2d) respectively where d is a common difference.

⇒ a + a + d + a + 2d = 6

⇒ 3a + 3d = 6

⇒ a + d = 2

Then,

⇒ a × (a + d) × (a + 2d) = 6

⇒ a × (a + d + d) = 6/2 = 3

⇒ a × (2 + d) = 3

⇒ (2 - d) × (2 + d) = 3

⇒ 4 - d² = 3

⇒ d² = 1

⇒ d = +-1

When, d = -1 then a = 3

When d = 1, then a = 1

∴ Three numbers = 3, 2, 1 or 1, 2, 3

Fill in the blank with the CORRECT determiner in the given sentence:

Even though I made a _______ mistakes, I think I spoke well.

((a))
some
((b))
any
((c))
little
((d))
few

Show Answer

Answer: ((d))

few

The correct answer is 'few'.

Key Points

'A little' and 'a few' are quantifiers meaning ‘some’.
We use 'a few' with plural countable nouns.
We use the word 'few' when we want to talk about the quantity of something. Usually, we use it when we want to talk about a small quantity.
Example: Few members of the family leave their hometown each year.
In the sentence above, we used few to indicate that only one or two members of the family leave town, most of them stay put.
Example: A few members of the family leave their hometown each year.
Here we’re saying that some members of the family leave their hometown. It’s still not a lot of them, but the emphasis is on the fact that there are some who do leave, and not that their number is small.
In the given sentence' mistakes' is the plural countable noun, so, 'few' is the most appropriate determiner.
Hence, option 4 is the correct answer.

The complete sentence is: Even though I made a few mistakes, I think I spoke well.

Additional Information

We use 'some' in affirmative sentences and 'any' in negative sentences and questions.
Example: Is there any sugar in the cupboard?

I have some questions to ask you.

Both 'some' and 'any' can be used before countable and uncountable nouns. But if we use them before a countable noun, the noun must be in the plural form.
Example: Are there any students in the classroom?
We use (a) little before uncountable nouns.
Example: He always gets good results with very little effort.

Hinglish

'A little' और 'a few' quantifiers हैं जिसका अर्थ है 'some'
हम plural counatble nouns के साथ 'a few' का उपयोग करते हैं।
जब हम किसी चीज की मात्रा के बारे में बात करना चाहते हैं तो हम 'few' शब्द का प्रयोग करते हैं। आमतौर पर हम इसका इस्तेमाल तब करते हैं जब हम थोड़ी मात्रा के बारे में बात करना चाहते हैं।
उदाहरण: Few members of the family leave their hometown each year.
ऊपर दिए गए वाक्य में, हमने यह इंगित करने के लिए few का उपयोग किया है कि परिवार के केवल एक या दो सदस्य शहर छोड़ते हैं, उनमें से अधिकांश वहीं रहते हैं।
उदाहरण: A few members of the family leave their hometown each year.
यहां हम कह रहे हैं कि परिवार के कुछ सदस्य अपना गृहनगर छोड़ देते हैं। यह अभी भी उनमें से बहुत कुछ नहीं है, लेकिन इस तथ्य पर जोर दिया गया है कि कुछ ऐसे भी हैं जो छोड़ देते हैं, और यह नहीं कि उनकी संख्या कम है।
दिए गए वाक्य में 'mistakes' plural countable noun, इसलिए 'few' सबसे उपयुक्त determiner है।
अतः विकल्प 4 सही उत्तर है।
हम affirmative sentences में 'some' और negative sentences और प्रश्नों में 'any' का उपयोग करते हैं।
उदाहरण: Is there any sugar in the cupboard?

I have some questions to ask you

Countable and uncountable nouns से पहले 'some' और 'any' दोनों का प्रयोग किया जा सकता है। ले��िन अगर हम गणनीय संज्ञा से पहले उनका उपयोग करते हैं, तो संज्ञा बहुवचन रूप में होनी चाहिए।
उदाहरण: Are there any students in the classroom?
हम uncountable nouns से पहले (a) little का उपयोग करते हैं।
उदाहरण: He always gets good results with very little effort.

पूरा वाक्य है: Even though I made a few mistakes, I think I spoke well.

When forces are applied to a body while it is still in static equilibrium, the body is deformed to varying degrees, depending on the nature of the body's material and the size of the deforming force.
Many materials have deformation that is not visible to the naked eye, but it exists.
When a body is subjected to a deforming force, it develops a restoring force.
This restorative force has the same magnitude as the applied force but is exerted in the opposite direction.
Stress is defined as the restoring force per unit area.
If F is the applied force and A is the body's cross-sectional area,
The magnitude of the stress = $Force \over Area$
The SI unit of stress is N m^–2or pascal (Pa).
The dimensional formula of Stress is [ ML^–1T^–2 ].

Key Points

In a typical stress-strain curve of a metal, the straight-line part in the graph indicates that Stress is directly proportional to strain.

A typical stress-strain curve for a metal

The line that connects O and A is a straight line in the above figure, This suggests that strain is directly related to stress, Hooke's Law is applicable in this area.
Hooke’s Law states that the strain of the material is proportional to the applied stress within the elastic limit of that material.
The material behaves like an elastic body in this area.

Show Answer

Answer: ((d))

x = 2 , y = 3

Given:

0.2 x + 0.3 y = 1.3 and 0.4 x + 0.5 y = 2.3

Calculation:

0.2 x + 0.3 y = 1.3 ----(1)

0.4 x + 0.5 y = 2.3 ----(2)

Multiply (1) by 2 then subtract (2) from it,

⇒ 0.4y + 0.6y = 2.6

⇒ 0.1y = 0.3

⇒ y = 3

Put value of y = 3 in any one equation,

⇒ 0.2x = 1.3 - 0.3 × 3

⇒ x = 2

∴ x = 2 and y = 3

Sum total of all the reaction taking place in a cell is known as:

((a))
Fermentation
((b))
Redox reaction
((c))
Esterification
((d))
Metabolism

Show Answer

Answer: ((d))

Metabolism

The correct answer is Metabolism.

Key Points

Sum total of all the reactions taking place in a cell is known as Metabolism.
It provides energy for vital processes and for synthesizing new organic material.
Metabolic reactions can be either anabolic or synthetic, in which energy is used to synthesise molecules.
Catabolic processes, in which molecules are broken down to liberate energy, could be the case.
The conversion of food energy into energy available to power cellular operations; the conversion of food into building blocks for proteins, lipids, nucleic acids, and certain carbohydrates; and the removal of metabolic wastes are the three basic functions of metabolism.
Living organisms are special in that they can collect energy from their surroundings and use it to perform activities like movement, growth, and reproduction.

Additional Information

Fermentation is a metabolic process in which a carbohydrate, such as starch or sugar, is converted into alcohol or acid by an organism.
Esterification is a chemical reaction that produces an ester (RCOOR) and water by combining alcohol (ROH) and an organic acid (RCOOH).
Redox reactions are oxidation-reduction chemical reactions in which the oxidation states of the reactants change.

Which of the following is the reason behind the rising of dough?

((a))
Multiplication of yeast
((b))
Emulsification of fat
((c))
Production of Carbon dioxide
((d))
Hydrogenation of oil

Show Answer

Answer: ((c))

Production of Carbon dioxide

The correct answer is Production of Carbon dioxide.

Key Points

The rising of dough during baking is due to the generation of carbon dioxide gas by yeast.
Adding yeast to the bread-making process consumes carbon molecules and converts them to alcohol and carbon dioxide.
Yeast reproduces quickly and emits carbon dioxide when it breathes.
Gas bubbles flood the dough, increasing its volume.
The employment of yeast in the baking business for manufacturing bread, pastries, and cakes is based on this principle.
It is used to make food items like idli, dosa, bread, etc.

Mistake PointsThe dough rises due to the production of carbon dioxide in the dough by the yeast, not due to the increase in the number of yeasts.

Additional Information

Fat emulsification is the process of combining fats into small clusters in the small intestine to increase their surface area.
Asexual reproduction through sprouting is the most common mechanism of vegetative development in yeast.
Hydrogenation is the process of converting a liquid unsaturated fat to a solid fat by adding hydrogen to it.

A copper rod of diameter 2 cm and length 10 cm is drawn into a wire of length 10 m of uniform thickness. Find the thickness of the wire.

((a))
1 mm
((b))
2 mm
((c))
0.1 mm
((d))
0.2 mm

Show Answer

Answer: ((b))

2 mm

Given:

Diameter = 2cm

Length = 10cm

Formula:

Volume of cylindrical rod = πr²h

Calculation:

Radius of rod = 2/2 = 1cm

Length of rod = height of rod = 10cm

Length of wire = height of wire = 10m = 1000cm

Volume of rod = π × 1² × 10 = 10π cm³

Volume of rod = Volume of wire

Volume of wire = 10π = π × r² × 1000

⇒ r² = 0.01

⇒ r = 0.1 cm

⇒ r = 1mm

∴ Thickness of wire = diameter of wire = 2r = 2mm

Which of the following statement is TRUE with respect to quantisation of charge?

((a))
There are two types of charges.
((b))
Charges are added algebraically.
((c))
Electrical charge is always an integral multiple of e.
((d))
Total charge of an isolated system is conserved.

Show Answer

Answer: ((c))

Electrical charge is always an integral multiple of e.

The correct answer is Electrical charge is always an integral multiple of e.

Key Points

Electrical charge is always an integral multiple of e is a TRUE statement with respect to quantisation of charge.
The charge 'q' on a body is always given by
q = ne
where 'n' is any integer(positive or negative)
All free charges are integral multiples of a basic unit of charge denoted by e.
The charge that an electron or proton carries is the fundamental unit of charge.
Because the charge on an electron is assumed to be negative, the charge on an electron is written as –e, while the charge on a proton is written as +e.
The quantisation of charge refers to the fact that electric charge is always an integral multiple of e.
The quantisation of charge was first suggested by the experimental laws of electrolysis discovered by Faraday.
Millikan demonstrated it experimentally in 1912.

Electron microscope
((c))
Vernier calliper
((d))
Optical microscope

Show Answer

Answer: ((b))

Electron microscope

The correct answer is Electron microscope.

Key Points

Electron microscope is the most suitable instrument for measuring the size of an atom.
Electron microscopy is a very advanced technique in which the item to be studied is assaulted with an electron beam that has a wavelength about a million times shorter than visible light.
Electromagnetic lenses magnify the image magnified by the electron beam in an electron microscope.
The entire electron passage occurs in a vacuum, and the image created is viewed on a fluorescent screen rather than through an eyepiece.
Man Knoll, a German electrical engineer, and Ernst Ruska, a physicist, invented the prototype electron microscope in 1931.

Additional Information

A screw gauge is an instrument used to measure the diameter or radius or thickness of a thin wire or thickness of a thin metal sheet with utmost accuracy.
Vernier callipers is an instrument used to measure linear dimensions.
The optical microscope is a type of microscope that uses visible light and a system of lenses to magnify images of small samples.

Show Answer

Answer: ((b))

I spent four hours at the mall but couldn’t find anything worth buying.

The correct answer is 'I spent four hours at the mall but couldn’t find anything worth buying'.

Key Points

'But' is used for joining two ideas or statements when the second one is different from the first one or seems surprising after the first one.
Example: We’re making good progress, but we’ve still got a long way to go.
In the given sentence, it is mentioned that in spite of spending four hours at the mall he couldn't find anything worth buying.
Therefore the most appropriate conjunction for the given statements is 'but'.
Hence, option 2 is the correct answer.

The correct sentence is: I spent four hours at the mall but couldn't find anything worth buying.

Additional Information

Consider this sentence: Although I am poor but I am happy.
There are two sentences: 'I am poor' and 'I am happy'.
The word ‘Although’ is a Conjunctive Adverb. When it is used to join the two sentences, it becomes “Although I am poor, I am happy”. So the conjunction “But” becomes redundant.
“I am poor” is the main or independent clause and ‘I am happy’ is the subordinate clause.
Both Although and But function as Subordinating Conjunction that is to join the main clause and the subordinate clause.
You can’t have two subordinating conjunctions in one sentence.

Hinglish

'But' दो विचारों या कथनों को जोड़ने के लिए प्रयोग किया जाता है जब दूसरा पहले से अलग होता है या पहले के बाद आश्चर्यजनक लगता है।
उदाहरण: We’re making good progress, but we’ve still got a long way to go.
दिए गए वाक्य में, यह उल्लेख किया गया है कि मॉल में चार घंटे बिताने के बावजूद उन्हें कुछ भी खरीदने लायक नहीं मिला।
इसलिए दिए गए कथनों के लिए सबसे उपयुक्त conjunction 'but' है।
अतः विकल्प 2 सही उत्तर है।
इस वाक्य पर विचार करें: Although I am poor but I am happy.
दो वाक्य हैं: 'I am poor' and 'I am happy'.
'Although' शब्द एक conjunctive adverb है। जब दो वाक्यों को जोड़ने के लिए इसका प्रयोग किया जाता है, तो यह "Although I am poor, I am happy" बन जाता हूं। तो conjunction "but" redundant हो जाता है।
“I am poor” मुख्य या स्वतंत्र clause है और ‘I am happy’ subordinate clause है।
Although और but दोनों subordinate conjunctions के रूप में कार्य करते हैं जो main cluase और subordinate clause में शामिल होना है।
आपके पास एक वाक्य में दो subordinate conjunctions नहीं हो सकते।

सही वाक्य है: I spent four hours at the mall but couldn't find anything worth buying.

Which term of the arithmetic progression 21,18,15,… is -75?

((a))
36
((b))
33
((c))
34
((d))
35

Show Answer

Answer: ((b))

Given:

AP = 21,18,15,…

Formula:

a = first term and d = common difference

Tn = a + (n - 1)d

Calculation:

d = 18 - 21 = -3

Then,

⇒ -75 = 21 + (n - 1) × -3

⇒ -75 = 21 - 3n + 3

⇒ n = 33

∴ -75 is the 33th term of given AP.

Identify the law that is related to the state of thermal equilibrium achieved by two systems.

((a))
Joule's law of heating
((b))
Zeroth law of thermodynamics
((c))
First law of thermodynamics
((d))
Second law of thermodynamics

Show Answer

Answer: ((b))

Zeroth law of thermodynamics

The correct answer is Zeroth law of thermodynamics.

Key Points

Zeroth law of thermodynamics is one of the four laws of thermodynamics.
Its creation is credited to Ralph H. Fowler.
The zeroth law of thermodynamics frames the concept of temperature as an indicator of thermal equilibrium.
According to the Zeroth Law of Thermodynamics, "two systems in thermal equilibrium with a third system separately are in thermal equilibrium with each other."
The Zeroth Law plainly states that when two systems A and B are in thermal equilibrium, there must be a physical quantity that has the same value for both.
Temperature is a thermodynamic variable whose value is the same for two systems in thermal equilibrium (T ).

Additional Information

The first law of thermodynamics states that energy can neither be created nor destroyed, only altered in form.
The total entropy of an isolated system (the thermal energy per unit temperature that is unavailable for doing productive work) can never decrease, according to the second law of thermodynamics.
When a current 'i' travels through a conductor of resistance 'r' for time 't,' Joule's law of heating states that the heat created in the conductor is equal to the product of the square of the current, the resistance, and the duration.

The chromosomes align themselves at equator plate during which of the following stage?

((a))
Metaphase
((b))
Telophase
((c))
Anaphase
((d))
S phase

Show Answer

Answer: ((a))

Metaphase

The correct answer is Metaphase.

Key Points

The chromosomes align themselves at the equator plate during Metaphase
The second phase of mitosis begins when the nuclear envelope completely disintegrates, and the chromosomes are distributed throughout the cell's cytoplasm.
Chromosome condensation is complete at this point, and they may be seen clearly under the microscope.
This is the stage at which the morphology of chromosomes may be investigated the most easily.
The metaphase chromosome is made up of two sister chromatids kept together by the centromere at this time.
The metaphase plate is the plane in which the chromosomes align during metaphase.
Metaphase is characterised by the following characteristics:
Spindle fibres attach to chromosomal kinetochores.
Through spindle fibres, chromosomes are transported to the spindle equator and positioned along with the metaphase plate to both poles.

Additional Information

The following important events characterise the anaphase stage:
Centromeres detach, and chromatids split.
Chromatids move from one pole to the other.
The chromosomes that have reached their respective poles decondense and lose their identity at the start of telophase.
S or synthesis phase marks the period during which DNA synthesis or replication takes place.

This biryani is very bland. I _______ have liked it better, had it been spicier.

((a))
must
((b))
would
((c))
can
((d))
ought to

Show Answer

Answer: ((b))

would

The correct answer is 'would'.

Key Points

'Would' is the past tense form of 'will'.
Because it is past tense, it is used to talk about the past, to talk about hypotheses (when we imagine something, and for politeness.
We use 'would' to make hypotheses:
Example: It would be very expensive to stay in a hotel.
In the given sentence, the person is imagining that if the biryani would have been spicier he would have liked it better.
Therefore. the most appropriate modal for the given blank is 'would'.
Hence, option 2 is the correct answer.

The correct sentence is: This biryani is very bland. I would have liked it better, had it been spicier.

Additional Information

You use 'must' to indicate that you think it is very important or necessary for something to happen.
Example: What you wear should be stylish and clean, and must definitely fit well.
You use 'can' when you are mentioning a quality or fact about something which people may make use of if they want to.
Example: Chicken is also the most versatile of meats. It can be roasted whole or in pieces.
You use 'ought to' to mean that it is morally right to do a particular thing or that it is morally right for a particular situation to exist, especially when giving or asking for advice or opinions.
Example: If you get something good, you ought to share it.

Hinglish

'Would' 'will' का भूतकाल का रूप है।
क्योंकि यह भूतकाल है, इसका उपयोग अतीत के बारे में बात करने के लिए, परिकल्पनाओं के बारे में बात करने के लिए किया जाता है (जब हम किसी चीज़ की कल्पना करते हैं, और विनम्रता के लिए।
हम परिकल्पना बनाने के लिए 'would' का उपयोग करते हैं:
उदाहरण: It would be very expensive to stay in a hotel.
दिए गए वाक्य में व्यक्ति यह कल्पना कर रहा है कि यदि बिरयानी अधिक तीखी होती तो उसे अधिक अच्छा लगता।
इसलिए दिए गए रिक्त स्थान के लिए सबसे उपयुक्त modal 'would' है।
अत: विकल्प 2 सही उत्तर है।
आप यह इंगित करने के लिए 'must' का उपयोग करते हैं कि आपको लगता है कि कुछ होने के लिए यह बहुत महत्वपूर्ण या आवश्यक है।

Fill in the blank with the CORRECT determiner in the given sentence:

Except for _______ who are sick, no student is allowed to be absent for the exam.

((a))
many
((b))
few
((c))
those
((d))
each

Show Answer

Answer: ((c))

those

The correct answer is 'those'.

Key Points

'Those' is used to point to people and things.
'These' and 'those' are plural. We use them as determiners and pronouns.
They are used with plural nouns.
Example: I need to paint those windows.
Therefore in the given sentence, 'those' will be the correct answer because it is pointing to the students who are sick.
Hence, option 3 is the correct answer.

The complete sentence is: Except for those who are sick, no student is allowed to be absent for the exam.

Additional Information

We normally use this, that, these, and those as pronouns to refer to things or ideas.
Example: What color are those? Black or dark blue. I can’t see.
We use that and those most commonly to point to things and people which are not easy to identify in a situation. They are often more distant from the speaker, and sometimes closer to the listener.
Example: Could you blow out those candles near you?

Hinglish

'Those' का प्रयोग लोगों और चीजों को इंगित करने के लिए किया जाता है।
'These' और 'those' बहुवचन हैं। हम उन्हें determiners और pronouns के रूप में उपयोग करते हैं।
इनका प्रयोग बहुवचन संज्ञाओं के साथ किया जाता है।
उदाहरण: I need to paint those windows.
अतः दिए गए वाक्य में 'those' सही उत्तर होगा क्योंकि यह उन विद्यार्थियों की ओर इशारा कर रहा है जो बीमार हैं।
अत: विकल्प 3 सही उत्तर है।
हम आम तौर पर चीजों या विचारों को संदर्भित करने के लिए this, that, these और those सर्वनाम के रूप में उपयोग करते हैं।
उदाहरण: What colour are those? Black or dark blue. I can’t see.
हम that और those चीजों और लोगों को इंगित करने के लिए सबसे आम तौर पर उपयोग करते हैं जिन्हें किसी स्थिति में पहचानना आसान नहीं होता है। वे अक्सर वक्ता से अधिक दूर होते हैं, और कभी-कभी श्रोता के अधिक निकट होते हैं।
उदाहरण: Could you blow out those candles near you?

What amount gets Rs.225 simple interest in 3 years at 10% rate interest per annum?

((a))
Rs.570
((b))
Rs.900
((c))
Rs.705
((d))
Rs.750

Show Answer

Answer: ((d))

Rs.750

Given:

SI = Rs.225, R = 10% and N = 3 years

Formula:

SI = PNR/100

Where, P = Principal, R = rate of interest and N = Time

Calculation:

⇒ 225 = P × 10 × 3/100

⇒ P = 750

∴ Amount is Rs.750.

Fill in the blanks with the appropriate tense in the given sentence:

When most people _______ the word 'concierge' they _______ of a hotel employee ready to assist guests.

((a))
hears, are thinking
((b))
heard, thought
((c))
are hearing, thought
((d))
hear, think

Show Answer

Answer: ((d))

hear, think

The correct answer is 'hear, think'.

Key Points

With verbs, only those with a third-person singular noun or pronoun (he, she, boat, courage) as a subject we add an 's' to the end.
Example: He talks too much.
Verbs with plural nouns and pronouns do not add 's' at the end.
Example: The people talk.
So, in the first blank 'hear' will be the correct answer.
Because the sentence is in the present tense, therefore, 'think' will be the most appropriate answer for the second blank.
'Thought' is the 3rd form of 'think' therefore, option 2 and option 3 are eliminated.
Option 1 is incorrect because 'hears' is used with the singular third-person nouns.
Hence, option 4 is the correct answer.

The correct sentence is: When most people hear the 'Concierge' they think of a hotel employee ready to assist guests.

Additional Information

Present Tense can be defined as an expression for an activity that is currently in action or is habitually performed. It is used for a state that generally exists or is currently ongoing.

Hinglish

क्रियाओं के साथ, केवल एक subject के रूप में एक third person singular संज्ञा या सर्वनाम के साथ हम अंत में एक 's' जोड़ते हैं।
उदाहरण: He talks too much.
बहुवचन संज्ञा और सर्वनाम वाले क्रिया अंत में 's' नहीं जोड़ते हैं।
उदाहरण: The people talk.
अतः पहले रिक्त स्थान में 'hear' सही उत्तर होगा।
चूंकि वाक्य present tense में है, इसलिए दूसरे रिक्त स्थान के लिए 'think' सबसे उपयुक्त उत्तर होगा।
'Thought' 'think' का third form है, इसलिए विकल्प 2 और विकल्प 3 समाप्त हो गए हैं।
विकल्प 1 गलत है क्योंकि 'hears' का प्रयोग singular third person संज्ञा के साथ किया जाता है।
अतः विकल्प 4 सही उत्तर है।
Present tense को किसी गतिविधि के लिए एक अभिव्यक्ति के रूप में परिभाषित किया जा सकता है जो वर्तमान में क्रिया में है या आदतन की जाती है। इसका उपयोग उस राज्य के लिए किया जाता है जो आम तौर पर मौजूद है या वर्तमान में चल रहा है।

सही वाक्य है: When most people hear the 'Concierge' they think of a hotel employee ready to assist guests.

In a single throw of a dice, what is the probability of getting a number greater than 3?

$\frac{3}{2}$
((c))
$\frac{2}{1}$
((d))
$\frac{2}{3}$

Show Answer

Answer: ((a))

$\frac{1}{2}$

Given:

Sample set in single throw of dice = {1,2,3,4,5,6}

Calculation:

n(S) = 6

Number of outcomes of getting a number greater than 3 = 3

∴ probability of getting a number greater than 3 = 3/6 = 1/2

Show Answer

Answer: ((d))

Dispersed phase is solid and dispersion medium is liquid.

Dispersed phase is solid and dispersion medium is liquid is NOT correct.

Key Points

Emulsions are liquid-liquid colloidal systems
Shaking a mixture of two immiscible or slightly miscible liquids produces an emulsion, which is a coarse dispersion of one liquid in the other.
Both dispersed phase and dispersion medium are liquids.
Emulsions are heterogeneous mixtures.
Milk is an emulsion.
In milk, water acts as a dispersion medium.
Oil-in-water emulsions are unstable, and on standing, they can split into two layers.
Any amount of dispersion medium can be used to dilute emulsions.
Heating, freezing, centrifuging, and other methods can be used to separate emulsions into constituent liquids.
Sol is a type of colloidal solution in which the dispersed phase is solid and the dispersion medium is liquid.

In a potentiometer of 10 wires, the balance point is obtained on the 7^th wire. To shift the balance point to the 9^th wire, we should:

((a))
Increase resistance in the main circuit
((b))
Decrease resistance in series with the cell whose emf is to be measured
((c))
Decrease resistance in the main circuit
((d))
Increase resistance in series with the cell whose emf is to be determined

Show Answer

Answer: ((a))

Increase resistance in the main circuit

The correct answer is increased resistance in the main circuit.

In a potentiometer of 10 wires, the balance point is found on the 7th wire.
To move the balance point to the 9th wire, we must increase the resistance in the main circuit.

Key Points

To shift the balance point to the 9 wire, the potential gradient of the wire needs to be decreased such that the balance point shifts further. By doing this the current in the main circuit will be decreased.
And the current in the circuit can only be decreased by increasing the resistance of the main circuit.

A toy is in the form of a cone mounted on a hemisphere of common base radius 7 cm. The total height of the toy is 31 cm. Find the total surface area of the toy $\left(\text use \pi = \frac{22}{7}\right)$

((a))
785 sq. cm
((b))
858 sq. cm
((c))
885 sq.cm
((d))
588 sq. cm

Show Answer

Answer: ((b))

858 sq. cm

Given:

Base radius = 7cm

Total height of toy = 31 cm

Formula:

The total surface area of cone = πrl

The curved surface area of hemisphere = 2πr²

Calculation:

Height of cone = 31 - 7 = 24 cm

Using pythagoras theorem,

(Slant height of cone)²= 24² + 7² = 625

Slant height of cone = 25 cm

Then,

Total surface area of toy = πrl + 2πr²

= 22/7 × (25 × 7 + 2 × 7²)

= 858

∴ Total surface area of toy is 858 sq.cm

A group of friends had planned for a trip and estimated the cost for food as Rs.2160.Seven of them did not come to the trip and hence rest of them had to pay Rs.28 each extra for the food. How many of them actually joined the trip?

((a))
20
((b))
15
((c))
10
((d))
27

Show Answer

Answer: ((a))

Given:

Cost of food = Rs.2160

Calculation:

Let original number of friends in a group be a.

Amount to be paid by one person in a group = 2160/a

Number of friends come for the trip = a - 7

Amount paid by one person in a group = (2160/a) + 28 = 2160/(a - 7)

Then,

⇒ 2160/a + 28 = 2160/(a - 7)

⇒ 28 = 2160/(a - 7) - 2160/a

⇒ 28(a² - 7a) = 2160 × 7

⇒ a² - 7a - 540 = 0

⇒ a² - 27a + 20a - 540 = 0

⇒ a(a - 27) + 20(a - 27) = 0

⇒ (a - 27)(a + 20) = 0

a = 27 or a = -20

Original number of friends in a group is 27.

∴ Number of persons actually joined the trip = 27 - 7 = 20

Which command would you use to save a document for the first time?

((a))
Save As
((b))
Recent
((c))
Save for the first time
((d))
Save

Show Answer

Answer: ((a))

Save As

The correct answer is Save As.

Key Points

Save and Save As are the two options for saving a file in Word.

These choices operate in a similar manner, with a few key distinctions.

Save:

You'll use the Save command to save your changes when you're creating or editing a document.
But to save the document for the first time the Save as is used, because the document reader asks for the user preference that in which type the user wants to save the following document.
The majority of the time, you'll use this command.
You'll only have to specify a file name and location the first time you save a file.
After that, you may save it with the same name and location by using the Save command.

Save As:

Save As command will be used to make a copy of a document while maintaining the original.
When you choose Save As, you'll need to give the cloned version a new name and/or location.

NOTE:

While traditionally "Save As" has often been used for the first save, different applications can have different conventions. In many modern applications, including Microsoft Word and Google Docs, you're correct that "Save" or auto-saving is often used for the first save.
The "Save As" function is typically used when you want to save a new copy of the document with a different name or to a different location, while keeping the original document unchanged.

So, if we're talking about these modern applications:

Save

would be the correct answer for saving a document for the first time. However, please note that the exact behavior may depend on the specific software or application you're using.

((c))
growth
((d))
None of these

Show Answer

Answer: ((c))

growth

The correct answer is growth.

Key Points

Needs that impel creativity and innovation, along with the desire to have a productive impact on our surroundings are growth needs.
Clayton Alderfer’s ERG theory combines Maslow’s five needs into three need levels:
existence
relatedness
growth

Important Points

Existence needs include the various forms of material and physiological desires, such as food and water, as well as such work-related forms as pay, fringe benefits, and physical working conditions.
Relatedness needs to address our relationships with significant others, such as families, friendship groups, workgroups and professional groups.
Growth needs to impel creativity and innovation, along with the desire to have a productive impact on our surroundings.
Even though the priority of these needs differs from person to person, Alberger’s ERG theory prioritizes in terms of the categories’ concreteness.
Existence needs are the most concrete, and easiest to verify.
Relatedness needs are less concrete than existence needs, which depend on a relationship between two or more people.
Finally, growth needs are the least concrete in that their specific objectives depend on the uniqueness of each person.

Organizational structure is made up of key elements. Which of the following is NOT one of these elements?

((a))
Span of control
((b))
Centralization
((c))
Decentralization
((d))
Co-ordination

Show Answer

Answer: ((d))

Co-ordination

The correct answer is Co-ordination.

Key Points

A strategic, carefully planned organizational structure helps a business run effectively and efficiently.
Organizational structure’s six elements are the 6 building blocks that managers must use in developing and structuring organizational hierarchy.
The six basic elements of organizational structure are:
departmentalization
chain of command
span of control
centralization or decentralization
work specialization
degree of formalization
Departmentalization refers to how the organizational structure groups the company's functions, offices and teams.
Most organizations, from businesses to nonprofits to the military, utilize a chain of command. This helps eliminate inefficiencies by having each employee report to a single manager, instead of to several bosses.
An organization’s span of control defines how many employees each manager is responsible for within the company. There is no single type of span of control that’s ideal for all companies or even for all businesses in a specific industry.
Organizational structures also rest somewhere on a spectrum of centralization. Generally, more conservative corporate entities adopt a centralized structure. A decentralized system allows all levels of management the opportunity to give input on big-vision goals and objectives.
In any business, employees at all levels typically are given a description of their duties and the expectations that come with their positions. In larger companies, job descriptions are generally formally adopted in writing.
Formalization is the element that determines the company’s procedures, rules and guidelines as adopted by management.

((a))
32 ∶ 53
((b))
53 ∶ 32
((c))
55 ∶ 34
((d))
34 ∶ 55

Show Answer

Answer: ((c))

55 ∶ 34

Given:

Mohan : Sohan = 7 : 4

Mohan + Sohan = 77 years

Calculation:

Let Mohan's age and Sohan's age be M and S years respectively.

⇒ M = 7S/4

⇒ M + S - 77

⇒ 7S/4 + S = 77

⇒ S = 28

⇒ M = 77 - 28 = 49

Mohan's age after 6 years = 49 + 6 = 55 years

Sohan's age after 6 years = 28 + 6 = 34 years

∴ the ratio of their ages after 6 years = 55 : 34

protocol

Show Answer

Answer: ((b))

TCP

TCP stands for Transmission Control Protocol.

Key Points

The Transmission Control Protocol (TCP) is a transport protocol built on top of IP that ensures packet delivery reliability.
In Transmission Control Protocol communication, the two computers begin by establishing a connection via an automated process called a ‘handshake.’
Once this handshake is complete, the first computer will begin delivering data packets to the second.
TCP addresses many of the issues that arise with packet-based messaging, such as missing packets, out-of-order packets, duplicate transmissions, and malformed packets.
TCP communications specify the order in which data packets should be received and verify that they arrive in the correct sequence.
TCP specifies that if a packet does not arrive (due to congestion in intermediary networks) it be resent.

Additional Information

A server is a computer or system that across a network distributes resources, data, services, or programmes to other computers known as clients.
A socket is one of the two ends of a two-way communication link between two networked programmes.

Show Answer

Answer: ((b))

The logic follows here is:

Logic: We have to arrange the first of the English alphabet in reverse order.

The original order of the English alphabets:

Now writing in reverse order:

Z Y X W V U T S R Q P O N M L K J I H G F E D C B A.

Then, the 16th letter from the left side,

Z Y X W V U T S R Q P O N M L K J I H G F E D C B A.

The 16th letter from the left side = K

Now, the 9th letter to the right of the K,

Z Y X W V U T S R Q P O N M L K J I H G F E D C B A.

Thus we can see B is the 9th to the right of the 16th letter from the left in a backward (reverse) alphabet series.

The ratio of the speeds of A and B is 3 : 4. If A takes 15 min more than B to cover the same distance, how much time does B take to cover the distance?

((a))
45 min
((b))
60 min
((c))
50 min
((d))
40 min

Show Answer

Answer: ((a))

45 min

Given:

Speed of A : Speed of B = 3 : 4

Formula:

Speed = distance/time

Calculation:

Let speed of A and B be 3a kmph and 4a kmph respectively.

Time taken by B to cover d distance be t hours.

Time taken by A to cover same d distance = t + 15/60 = (t + 1/4) hours

Then,

⇒ 3a × (t + 1/4) = 4a × t

⇒ 3t + 3/4 = 4t

⇒ t = 3/4

⇒ t = 3/4 × 60 = 45 min

∴ Time taken by B is 45 min.

Shortcut TrickSpeed inversely proportional to the Time

Speed ratio A to B = 3 : 4

Time ratio A to B = 4 : 3

According to the question,

⇒ 4 - 3 = 1 unit

⇒ 1 unit = 15 min

So, the time is taken B cover the same distance = 3 × 15

⇒ 45 min

∴ Time taken by B is 45 min.

If ‘+’ stands for ‘Multiplication’

‘-’ stands for ‘Division’

‘×’ stands for ‘Subtraction’

‘÷’ stands for ‘Addition’

Then which of the following equation is CORRECT?

((a))
24＋32－12 × 6 ÷ 10－5 = 150
((b))
24 ÷ 32 × 12－6 ÷ 10－5 = 22
((c))
24 × 32 ÷ 12－6 × 10 ÷ 5 = 100
((d))
24 ÷ 32＋12－6 × 10 ÷ 5 = 83

Show Answer

Answer: ((d))

24 ÷ 32＋12－6 × 10 ÷ 5 = 83

The logic follows here is:

Symbols	+	-	×	÷
Meaning	×	÷	-	+

By checking options and inserting codes and then using BODMAS Rule:

(1) 24＋32－12 × 6 ÷ 10－5 = 150

LHS = 24 × 32 ÷ 12 - 6 + 10 ÷ 5

= 24 × 2.67 - 6 + 2

= 64.08 - 6 + 2

= 66.08 - 6

= 60 .08 ≠ 150

≠ RHS

(2) 24 ÷ 32 × 12－6 ÷ 10－5 = 22

LHS = 24 + 32 - 12 ÷ 6 + 10 ÷ 5

= 24 + 32 - 2 + 2

= 58 - 2

= 56 ≠ 22

≠ RHS

(3) 24 × 32 ÷ 12－6 × 10 ÷ 5 = 100

LHS = 24 - 32 + 12 ÷ 6 - 10 + 5

= 24 - 32 + 2 - 10 + 5

= 31 - 42

= - 11 ≠ 100

≠ RHS

(4) 24 ÷ 32＋12－6 × 10 ÷ 5 = 83

LHS = 24 + 32 × 12 ÷ 6 - 10 + 5

= 24 + 32 × 2 - 10 + 5

= 24 + 64 - 10 + 5

= 93 - 10

= 83

= RHS

Hence, 24 ÷ 32＋12－6 × 10 ÷ 5 = 83 is the correct answer.
