SSC CHSL Previous Paper 2 (Held On: 4 March 2018 Shift 3) (Previous Year Paper)

The correct answer is 'Arbitrates'

Explanation:   

• From the given options, only the word 'Arbitrates' is making any sense or is meaningful.
• The word 'Arbitrates' means to give an opinion about (something at issue or in dispute).
• It is in the simple present tense to indicate a general rule or a regular occurrence
• The synonyms of the word 'arbitrates' are "adjudge, adjudicate, decide, determine, judge, referee, rule (on), settle, umpire".
• The antonyms of the word 'arbitrates' are "equivocate, hedge, pussyfoot, skirt".
• Hence, the option 'arbitrates' is the correctly spelt word.
  

Extra- Bites-     

• Examples of 'arbitrates' in a sentence:
• The supreme court, which arbitrates on constitutional disputes but has not ruled against the government since 2003.
• The State Council arbitrates in disputed administrative matters and gives advice on all bills and decrees.

The context is saying that if the child has the ability convince his or her parents then they should be proud as the child has interpersonal skill sets. Using this chain of structure, A is the first sentence C is the second and B the third. Thus option 2 is the correct answer.

The clue “determine” says that it is in present tense. So “sowing” is inappropriate here. Likewise “had sow” is both grammatically invalid and in past tense. We say “as you sow so shall you reap.” Thus option 2 is the correct answer.

The correct answer is: Letting.

Key Points

• In the given sentence, "letting" functions as a gerund, which is a verb form that acts as a noun.
• Gerunds are formed by adding -ing to a verb and can be used as subjects, objects, or complements in a sentence.
• In the sentence "Opening the door to her each morning is like letting a breath of fresh air into my world," "letting" is a gerund functioning as the direct object of the verb "is like."
• The gerund phrase "letting a breath of fresh air into my world" is the object of comparison and is equivalent to "the act of letting a breath of fresh air into my world." It describes the action or process that is being compared to the act of opening the door.
• The gerund form "letting" is grammatically appropriate here because it helps convey the idea that the act of opening the door is similar to the act of allowing a breath of fresh air to enter one's world.
• It adds a sense of action and movement to the sentence, emphasizing the dynamic nature of the comparison.

Therefore, the correct answer is: Opening the door to her each morning is like letting a breath of fresh air into my world.

Key PointsThe word “chore (घर का काम) means “a routine task, especially a household one.” Thus option 1 is the correct choice. Other options won’t fit as:

Servitude=> the state of being a slave or completely subject to someone more powerful. (भृत्यभाव, दासत्व)

Moil=> work hard.(परिश्रम कार्य)

Travail=> painful or laborious effort. (कष्टपूर्ण या कड़ा परिश्रम)

The correct answer is "Stanchion".

Key Points

• Let us look at the meaning of all the words:
• Repose means a state of rest or peace.
• Example: "The cat was in repose on the couch."
• Stanchion means an upright bar, post, or frame forming a support or barrier.
• Example: "The stanchions held up the sign."
• Recumbent means lying down with the body supported on the back.
• Example: "The patient was recumbent in the bed."
• Supine means lying on the back with the face up.
• Example: "The doctor examined the patient in the supine position."
• From the meanings of all the words, it is clear that the best substitute of the words is "Stanchion".
• Thus option 2 is the correct answer.

The correct answer is: An implausible story used as an explanation or excuse.

Key Points

• Cock and bull story: an improbable tale told as justification. (स्पष्टीकरण या बहाने के रूप में इस्तेमाल की जाने वाली एक अनुमानित कहानी।) 
• For example: So you came all the way up here to tell me this cock-and-bull story!

Therefore, the correct answer is: An implausible story used as an explanation or excuse.

The correct answer is 'Paid for by someone'.

Key Points

• At somebody's expense means someone paying your expenses or what you should pay.(कोई आपके खर्चों का भुगतान कर रहा है या आपको क्या भुगतान करना चाहिए)
• For example: The document was printed at the taxpayer's expense.

Therefore, the correct answer is 'Option 1'. 

Additional Information

• To blame a crime on someone else(किसी और पर अपराध का आरोप लगाना)
• The unlucky persons who lose a race.(बदकिस्मत व्यक्ति जो एक दौड़ हार जाते हैं।)
• If one person benefits it is always at the loss of another. (यदि एक व्यक्ति को लाभ होता है तो दूसरे का हमेशा नुकसान होता है)

The context says what you experience throughout the day “shapes” or “builds” your degree of happiness or sorrow. So the only fit option is “makes up”. Other preposition are incorrect in the given context and will make the sentence erroneous. Thus option 1 is the correct answer.

The context talks about on whom you can rely and on whom you cannot. So we say the person who is “faithful” (on whom you can rely”. Thus option 1 is the only fit. Other options won’t fit as:

Faith is a belief by itself

Faithfulness is the tendency to have a faith

Faithfully is the faith or strong belief with which you do something or act.

When we talk to someone or about someone with reference to their someone we say “your friend”, “your fellow workers”, etc. Thus option 2 is the correct choice. All the other options makes the sentence incorrect or meaningless

The context or premise is talking about the fact as to how people look at you “and” the tone or way they speak to you. All other options makes the sentence erroneous. Thus option 4 is the correct answer.

Happy” should have a premise. In this context we say “one’s or a person’s happiness” so option 1 is the correct choice. Similarly “happily” is expression of doing something with enjoyment. Happiest can’t fit as it is a superlative degree of comparison and here there is nothing to which it is being compared. Thus option 1 is the correct choice.

The correct spelling is Assassination

Key Points

• The correct spelling of the word is 'Assassination' which means  the murder of a prominent or important person
• For e.g.- The assassination was reported in all the newspapers.
• Thus, option 3rd is correct therefore the answer.

Option 1 is changing the tense and meaning both “inform” and “to say” are two different things. Secondly it should be “informed”. Option 2 again changes to present whereas it should be “said that” and not “say”. This makes option 4 as the correct choice. Option 3 is just rephrasing and not indirect. Thus option 4 is the correct answer.

The correct answer is: The wounded men were being helped by some girls.

Key Points

• The given Active voice is in Past Continuous Tense.
• Its structure is as follows: Subject + was/were + (Verb+ing) + object.
• While changing it into Indirect form, its tense will remain same.
• Its Passive voice structure will be: Object(subjective case) + was/were + being + Verb₃ form + by + Subject(objective case). 
• ​Ex. Active: Ram was playing cricket.

                           Passive: Cricket was being played by Ram.

Hence, the correct answer is: The wounded men were being helped by some girls.

Additional Information

• Option 1 changes the meaning as if the wounded men were helping some girls. Hence, it is incorrect.
• Option 3 changes the context from past to present. Hence it is incorrect.
• Option 4 is in Simple Past tense. So, it is also incorrect.

The notion talks about the fact that many women rights are against their own culture trend and hence challenges the beliefs of the individual and community identity. Following this chain of logic, P is the first sentence followed by R and then ending with Q. Thus option 4 is the correct choice.

Being Baneful means to be destructive or harmful. So all the option except 4 gives a similar meaning. Thus lucky is the word which is opposite. Thus option 4 is correct choice. Lucky means “having, bringing, or resulting from good luck.”

Additional Information

• Harmful means something that is likely to be damaging, injurious (हानिकारक).
• Synonyms: detrimental, noxious, injurious, deleterious, bad
• Disastrous means extremely bad or unsuccessful​ (विनाशकारी).
• Synonyms: terrible.
• Cruel means extremely unkind and unpleasant (निर्मम, क्रूर)
• Synonyms: atrocious, barbarous, bitter, brutal

The correct answer is "Disheartened". 

Key Points

• The given word 'Elated' is an adjective in English, which refers to being very happy and excited. (खुश)
• For example, She was elated at the news of her promotion.
• The correct answer 'Disheartened' is also an adjective that refers to losing confidence or hope; discouraged. It is the opposite of elated. (निराश)
• For example, He was disheartened after the failure of his new venture.
• Therefore, the correct answer is- 'Option 3'.

Additional Information

• 'Inspired'(Option 1) in English refers to being stimulated or motivated to do or feel something. It does not signify the opposite of 'Elated'. (प्रेरित)
• 'Cheered'(Option 2) in English refers to giving comfort or support to someone.
• It can be seen as similar in meaning to 'Elated' and not its opposite. (खुश किया)
• 'Encouraged' (Option 4) in English refers to inspiring someone with the courage or confidence to do something, not the opposite of 'Elated'. (प्रोत्साहित)

The correct answer is "Abusive". 

Key Points

• The given word 'Invective' is an adjective which refers to a speech or piece of writing that attacks, insults, or vehemently criticizes a person, topic, or institution. (निंदा)
• For example, the politician's invective against his opponents generated a lot of controversy.
• The correct answer 'Abusive' is also an adjective that refers to a word or language causing harm or injury.
• It is a close synonym of invective and often used to describe offensive and insulting language. (अपमानजनक)
• For example, he was arrested for using abusive language in public.
• Therefore, the correct answer is- "Option 3".

Additional Information

• 'Invent'(Option 1) in English refers to creating, designing, or originating something that has not existed before. (आविष्कार करना)
• 'Expressive'(Option 2) in English refers to effectively conveying thought or feeling.

The correct answer is 'Laurels '.

Key Points

• Accolade- an award, honor, or instance of positive acknowledgment or praise (एक पुरस्कार, सम्मान, या सकारात्मक पावती या प्रशंसा का उदाहरण)
• For e.g.-  Her approval was the highest accolade he could receive.
• Laurels -  praise for a person because of something they have done ( किसी व्यक्ति के द्वारा किए गए किसी कार्य के कारण उसकी प्रशंसा करना)
• For e.g.- The player earned his laurels from years of hard work.

Additional Information Let's look at the meaning of other options-

• Silence - complete absence of sound.
• Mediocrity-  the quality or state of being mediocre
• Lowliness - Lack of vanity or self-importance

The sentence is trying to portray the contradiction that being happy keeps us well while negative thoughts yield illness. Thus option 1 is the correct choice. All other options reflect the same meaning i.e. being happy hence ruled out.

The subject intends to say that he or she will not be attending the party. So the only option to justify the statement keeping the tense at place is “shall”. Thus option 4 is the correct answer. Other options won’t fit as:

“Probably be” makes the sentence erroneous

“will be” should be followed by not “attending” and not “attend”

If using “won’t” then it should not be followed by “not

Part 1 has error. The sentence talking about the procedure as to how to a bill gest passed. Using”could” makes the sentence grammatically incorrect. It should be “Money bills can only be introduced in the lok sabha"Thus Option 1 is the correct choice.

Correct answer is '2'.

Key Points

• The given sentence is in 'past Tense'
• second form of verb will be used in the given sentence
• Thus, 'amusing' will be replaced with 'amused' to make the sentence contextually and grammatically correct 
  

Correct sentence- She was quite amused at that story.

The pattern followed here is:-

Lotus comes under the category of Flowers.

1. Rabbit comes under the category of Mammals.

2) Peacock comes under the category of Bird.

3. Crow comes under the category of Bird.

4. Krishna comes under the category of God.

Hence, the correct answer is "Peacock : Bird".

The Logic followed here is:-

Second number = (First number)² - 2

In 13 : 167

167 = (13)² - 2

= 169 - 2

= 167

Similarly,

In 23 : ?

? = (23)² - 2

= 529 - 2

= 527

Hence, the correct answer is "527".

The pattern followed here is:-

PIR is related to OHQ as

Similarly, FAX is related to EZW as

Hence, the correct answer is "FAX : EZW".

Given:-

1) Carnivorous – Tiger → Sequence followed (Food Habits – Animals)

2) Herbivorous – Cow → Sequence followed (Food Habits – Animals)

3) Rabbit – Herbivorous → Sequence doesn't follow (Animals – Food Habits)

4) Omnivorous – Dog → Sequence followed (Food Habits – Animals)

Therefore, Only Rabbit – Herbivorous is given in reverse order i.e. Animal and its class based on food habit.

Hence, the correct answer is "Rabbit – Herbivorous".

The Logic followed here is:-

Number = (Number)²

64 = (8)²→ 64

36 = (6)² → 36

16 = (4)² → 16

12 ≠ (2)² = 4

Hence, the correct answer is "2 – 12".

The pattern followed here is:-

S + 4 = W

G + 4 = K

F + 4 = J

D + 3 = G

As can be seen that DG doesn't follow the same pattern as the other three.

Hence, the correct answer is "DG".

The correct order of the given words as they would appear in an English dictionary is as follows:-

2. Cigar

3. Cinema

4. Clause

5. Clever

6. Client

As can be seen the word that comes at First position is Cigar.

Hence, the correct answer is "Cigar".

The pattern followed in the given series is:

Hence the correct answer is "KP".

Given:-

Position of Rahul from Top = 19th

Position of Ajay from Bottom = 21st

After interchanging:

Position of Ajay from Bottom = 28th

Total number of boys in row = Position of Rahul from Top (Before interchanging) + Position of Ajay from Bottom (After interchanging) - 1

Total students = 19 + 28 - 1 ⇒ 46

Hence, the correct answer is "46".

1. Lite: LIABILITIES, hence word can be formed.

2. Able: LIABILITIES, hence word can be formed.

3. Like: ‘K’is not present in LIABILITIES, hence word cannot be formed.

4. Table: LIABILITIES, hence word can be formed.

Hence, the correct answer is "Like".

The pattern followed here is:-

HARMS is written as 81181319

And,

FLUTE is written as 61221205

Similarly,

WOUND is written as 231521144

Given: 8 ÷ 14 - 20 + 5 × 2

Changing symbols as per the given information

We get,

8 + 14 × 20 ÷ 5 - 2

Using BODMAS,

= 8 + 14 × 4 - 2

= 8 + 56 - 2

= 64 - 2

= 62

Hence, the correct answer is "62".

Given:-

12 - 6 × 5 + 20 ÷ 4 = 31

Checking options one by one by interchanging signs:-

1) + and ÷

12 – 6 × 5 ÷ 20 + 4 = 31

Now after applying BODMAS rule, we get:- = 17.5 ≠ 31

12 – 6 × 5 ÷ 20 + 4 = 31

12 – 6 × 0.25 + 4 = 31

12 – 1.5 + 4 = 31

16 - 1.= 31

14.5 ≠ 31

2) + and ×

12 – 6 + 5 × 20 ÷ 4 = 31 

Now after applying BODMAS rule, we get:- 

12 – 6 + 5 × 20 ÷ 4 = 31 

12 – 6 + 5 × 5 = 31 

12 – 6 + 25 = 31 

37 - 6 = 31 

31 = 31

3) - and +

12 + 6 × 5 – 20 ÷ 4 = 31

Now after applying BODMAS rule, we get:- 

12 + 6 × 5 – 20 ÷ 4 = 31

12 + 6 × 5 – 5 = 31

12 + 30 – 5 = 31

42 - 5 = 31

37 ≠ 31

4) ÷ and ×

12 – 6 ÷ 5 + 20 × 4 = 31

Now after applying BODMAS rule, we get:-

12 – 6 ÷ 5 + 20 × 4 = 31

12 – 1.2 + 20 × 4 = 31

12 – 1.2 + 80 = 31

92 – 1.2 = 31

90.8 ≠ 31

Hence, the correct answer is "+ and ×".

The pattern followed here is,

70 * 10 = 70 ÷ 10 = 7 = -7

50 * 5 = 50 ÷ 5 = 10 = -10

10 * 2 = 10 ÷ 2 = 5 = -5

Similarly,

80 * 1 = 80 ÷ 1 = 80 = -80

Hence, the correct answer is "-80".

The logic followed here is:

Hence, the correct answer is "XyxYXYXY".

1)Truck A goes 6 km North, then turns to its right and goes 4 km.

2) Truck B goes 9 km East, then turns North and goes 6 km, then turns to its right and goes 4 km. 

3) Two trucks start from the same warehouse so we combining two diagrams, we get

​

Hence, the correct answer is "9 km East".

The least possible diagram of this question is as follows,

3. 30, 96, 41, 69 → J, W, M, Y

4. 24, 77, 22, 78 → H, V, D, S

Hence, the correct answer is "95, 14, 85, 78".

Applying BODMAS Rule, Bracket, of, Division, Multiplication, Addition, Subtraction

⇒ b - [b - (a + b) - {b - (b - a - b)} + 2a]

⇒ b - [b - (a + b) - (b + a) + 2a]

⇒ b - [b - a - b - b - a + 2a]

⇒ b + b = 2b

Given problem can be written as (200 + 13) (200 + 13) + (200 - 13) (200 -13)

⇒ (200 + 13)² + (200 -13)²

We know that (x + y)² + (x - y)² = 2 (x² + y²)

So, the solution is 2 × (200² + 13²) = 2 × (40000 + 169) = 2 × 40169 = 80338

∴ Required value is 80338

If f(x) is divided by (x + a), then the remainder is derived by substituting x = -a in the given expression

For the given problem, the remainder is obtained by substituting x = -2 in the given expression

f(-2) = 4 (-2)⁴ + 10 (-2)³ - 20 (-2)² + 90

⇒ (4 × 16) + (10 × -8) - (20 × 4) + 90 = (64 - 80 - 80 + 90) = (154 - 160) = -6

∴ Remainder = -6

Given x - y = 5 and x² + y² = 45

From the Algebraic Identity, we know that (x - y)² = x² + y² - 2xy

xy = [(x² + y²) - (x - y)²]/2             ----(1)

Substituting the values of (x - y) and (x² + y²) in Equation 1, we get

xy = [45 - (5)²]/2

⇒ xy = (45 - 25)/2 = 20/2 = 10

∴ Value of xy = 10

Given:

largest angle = 80°

Calculation:

Smallest angle = Largest angle - 40° = 80° - 40° = 40°

We know that the sum of angles of a triangle = 180°

Third angle = 180° - (Sum of largest and smallest angle) = 180° - (80° + 40°) = 180° - 120° = 60°

∴ Third angle = 60°

Considering triangle ABC and triangle ADE

∠A = ∠A (common)

∠ABC = ∠ADE (corresponding angles)

By AA rule triangle ABC ≈ triangle ADE

So, AB/AD = BC/DE = AC/AE

From the basic proportionality theorem, if a line DE is drawn parallel to intersect the other two sides in distinct points, then the other two sides are divided in the same ratio.

So, the correct option is AD/DB = AE/EC

Given:

Price of 1kg of sugar increased by 30%

Increase = 48

Calculation:

Let the price of 1 kg of sugar = ‘X’ Rs

If the price is increased by 30%, then the new price = X + (30% of X) = X + 0.3X = 1.3X

Given the increase in the price = Rs. 48

⇒ (1.3X - X) = 48

⇒ 0.3X = 48

⇒ X = 48/0.3 = Rs.160

New Price = 1.3X = 1.3 × 160 = Rs. 208

∴ Required answer = Rs. 208

Let the three numbers be x, y, z

Given x : y = 3 : 5, y : z = 4 : 7

In both the ratios, the common term is ‘y’. Make the value with respect to ‘y’ same in both the ratio

Multiply both numerator and denominator on other side of the ratio (x : y) with 4 and of ratio (y : z) with 5, we get

x : y = (3 × 4) : (5 × 4), y : z = (4 × 5) : (7 × 5)

⇒ x : y = 12 : 20, y : z = 20 : 35

Combining both the ratios we get, x : y : z = 12 : 20 : 35

Let x = 12k, y = 20k, z = 35k

Given the sum, (12k + 20k + 35k) = 67

⇒ k = 1

So, x = 12, y = 20, z = 35

∴ Second number = 20

A invested Rs. 1800 for 12 months, B invested Rs. 3600 for (12 - 4 = 8 months), C invested Rs. 1200 for (12 - 6 = 6 months)

We know that if both the Investment and Time Periods are different, then the Profit will be divided in the ratio of the product of their Investment and Time Period

Ratio of the Profits = (1800 × 12) : (3600 × 8) : (1200 × 6) = 216 : 288 : 72 = 9 : 12 : 3

As the total profit is Rs. 1760, share of A = [9/(9 + 12 + 3)] × 1760 = (9/24) × 1760 = 660

∴ Share of A in the total profit = Rs. 660

Given:

Average of 8 consecutive integers is 23/2

Calculation:

Let the 8 consecutive integers be x, (x + 1), (x + 2), (x + 3), (x + 4), (x + 5), (x + 6), (x + 7)

Average = [x + (x + 1) + (x + 2) + (x + 3) + (x + 4) + (x + 5) + (x + 6) + (x + 7)]/8 = 23/2

⇒ (8x + 28) = (23/2) × 8 = 92

⇒ 8x = 92 - 28 = 64

⇒ x = 64/8 = 8

So, the first three numbers are 8, (8 + 1), (8 + 2)

Average of the first three integers = (8 + 9 + 10)/3 = 27/3 = 9

∴ Required Average = 9

Given Simple Interest (I) = Rs. 340, Rate of Interest (R) = 6%, Time Period (in years) = (8/12) = (2/3)

Formula for Simple Interest (I) = PTR/100

Sum (P) = 100I/TR = (100 × 340)/(2/3) × 6 = (100 × 340)/4 = Rs. 8500

∴ Principal (Sum) = Rs. 8500

Let the cost price be Rs. x.

Selling Price = Cost Price (1 + Profit%) = x (1 + 60%) = x (1.6) = 1.6x

Profit% on selling price = [(SP - CP)/SP] × 100% = [(1.6x - x)/1.6x] × 100% = [0.6x/1.6x] × 100%

⇒ (6/16) × 100% = 0.375 × 100 = 37.5%

∴ Profit Percentage = 37.5%

Given:

Marked price of an article = 520

Selling price = 384.8

Calculation:

Marked Price (MP) = Rs. 520, Selling Price = Rs. 384.8

Formula for Discount% = [(MP - SP)/MP] × 100% = [(520 - 384.8)/520] × 100%

⇒ (135.2/520) × 100% = 0.26 × 100% = 26%

∴ Discount Percentage = 26%

Given problem can be written as $5;\left[ {\frac{1}{{\sqrt 2 + 1}} + \frac{1}{{\sqrt 3 + \sqrt 2 }} + \frac{1}{{\sqrt 4 + \sqrt 3 }} + \ldots \frac{1}{{\sqrt {121} + \sqrt {120} }}} \right]$

Rationalising each term will make the denominator ‘1’ in each case

$5;\left[ {\frac{{\sqrt 2 - 1}}{1} + \frac{{\sqrt 3 - \sqrt 2 }}{1} + \frac{{\sqrt 4 - \sqrt 3 }}{1} + \ldots ..\frac{{\sqrt {121} - \sqrt {120} }}{1}} \right]$

It can be seen that all the terms in the bracket will cancel except -1 and $\sqrt {121}$

5 (-1 + 11) = 5 × 10 = 50

∴ Required answer = 50

Ram’s one day work = (1/5), Shyam’s one day work = (1/9)

Ram and Shyam will divide the wages in the ratio of their one day’s work = (1/5) : (1/9) = 9 : 5

Amount received by Ram = [9/(9 + 5) × 5600] = [9/14 × 5600] = Rs. 3600

Amount received by Shyam = [5/(9 + 5) × 5600] = [5/14 × 5600] = Rs. 2000

Difference in the amount = Rs. (3600 - 2000) = Rs. 1600

∴ Required difference = Rs. 1600

Given:

Speed of the train = 40 km/hr

Speed of the Person (while walking) = 8km/hr

Time taken = 12 hours

Formula used:

Time taken = Distance/Speed

Calculation:

Time taken by the train at a speed of 40 kmph + Time taken by walking at 8 kmph = 12 hours 

Let ‘d’ be the distance of one side travel

(d/40) + (d/8) = 12

⇒ (d + 5d)/40 = 12

⇒ d = (40 × 12)/6 = 80 kms

∴ One side distance = 80 kms.

From the graph, it is clear that the second highest value is for Marketing which is 450 (lakhs)

∴ Right answer is Marketing

Total expenditure in lakhs = (500 + 350 + 450 + 400 + 150 + 250 + 300) = 2400 lakhs

∴ Right answer is 2400

Total expenditure in lakhs = (500 + 350 + 450 + 400 + 150 + 250 + 300) = 2400 lakhs

That means 2400 combined measures an angle of 360°

So, for every 100, the angle represented = 360°/24 = 15°

Measure of central angle of sector representing Rent (400) = 4 × 100 = 4 × 15° = 60°

∴ Right answer is 60°

Total expenditure in lakhs = (500 + 350 + 450 + 400 + 150 + 250 + 300) = 2400 lakhs

Total expenditure in Sales and Marketing together = 350 + 450 = 800 lakhs

To find 800 is what percent of 2400

Required Percentage = (800/2400) × 100 = (1/3) × 100 = 33.33%

∴ Right answer is 33.33%

Given:

Side of the equilateral triangle = 8 cm

Formula used:

Area of equilateral triangle = √3a2/4

Calculation:

So, Area = √3a²/4 = √3 × 8 × 8/4 = 16√3 cm²

Area of the circle = πr² (where ‘r’ is the radius of the circle)

Given πr² = 346.5

⇒ (22/7) × r² = 346.5

⇒ r² = 346.5 × (7/22) = 110.25

⇒ r = √110.25 = 10.5 cm

∴ Circumference of the circle = 2πr = 2 × (22/7) × 10.5 = 66 cm

Total surface area of a cube of side ‘a’ = 6a²

From the problem, Total surface area = 6 × 7.5² = 6 × 56.25 = 337.5 cm²

∴ Right answer is 337.5 cm²

We know that tan 45° = 1

Value of (tan 45° + 1/√2) = 1 + (1/√2) = (√2 + 1)/√2

∴ Right answer is (√2 + 1)/√2

We know that cosec P = Hypotenuse/Opposite = PR/QR = 17/15

Let the sides PR and QR be 17x and 15x respectively

For the right-angled triangle, as per Pythagoras theorem, PQ² + QR² = PR²

PQ² = PR² - QR²

⇒ PQ² = (17x)² - (15x)² = 289x² - 225x² = 64x²

⇒ PQ = √64x² = 8x

From the figure, Sin R = PQ/PR = 8x/17x = (8/17)

∴ Sin R = (8/17)

The Correct answer is Herbivore > Carnivore

Explanation:

• Herbivores are animals that derive energy from just eating plants, whereas carnivores are those animals which derive their energy by eating meat or flesh of other animals.
• The small intestine of herbivores is longer in length than carnivores since plant matter is lower in nutrients and is tough to break as compared to animal matter. Therefore, animals who are herbivores need to be efficient digesters so that they can get the necessary amount of nutrients.

The Correct answer is 50

Concept:

• Ohm’s law: Ohm’s law states that at a constant temperature, the current through a conductor between two points is directly proportional to the voltage across the two points.

Voltage = Current × Resistance

V = I × R

V = voltage, I = current and R = resistance

The SI unit of resistance is ohms and is denoted by Ω.

• It helps to calculate the power, efficiency, current, voltage, and resistance of an element of an electrical circuit.
• If an element follows ohm’s law, then the element is known as a linear element.

Ex: Resistor

Calculation:

According to Ohm’s law,

V(Volts) = I(Ampere) * R(Ohms)

R = V/I

R = 5/0.1 = 50 Ω

The Correct answer is Uniformly.

Explanation:

• Velocity: The rate of change of displacement of a body is called the velocity of that body. It is a vector quantity that has both magnitudes as well as directions.
• Acceleration: The rate of change of velocity is called the acceleration of the body.
• Acceleration is also a vector quantity.
• The slope of any velocity-time graph gives an acceleration of the body.
• Uniform acceleration: When the acceleration is constant, then it is called uniform accelerated motion. It is also called uniformly variable motion.
• Non-uniform acceleration: When the acceleration is not constant, then the motion is non-uniformly accelerated motion.
• Since the acceleration of a uniform acceleration motion is constant. It doesn't change with time. The slope of the velocity-time graph gives acceleration. When the slope is constant (or a straight line) then the acceleration will be uniform/constant.
• The motion of a freely falling body is an example of uniformly accelerated motion.
• Uniform acceleration is a kind of motion in which the velocity of an object changes in every equal time period by an equal amount.

The Correct answer is Pressure.

Explanation:

When the pressure around an area decreases, then the wind speed increases and vice versa. The higher would be the pressure difference, the more would be the wind speed. This derives 2 major concepts:
