Given:

625 463 875 327 136

according to the given conditions, 

Add second and third digit of each number.

So, 

625 = add 2 and 5 = (2 + 5) = 7 (not divisible by 3)

463 = add 6 and 3 = (6 + 3) = 9 (divisible by 3)

875 = add 7 and 5 = (7 + 5) = 12 (divisible by 3)

327 = add 2 and 7 = (2 + 7) = 9 (divisible by 3)

136 = add 3 and 6 = (3 + 6) = 9 (divisible by 3)

Except "625" all the given number's second and third digit's sum is divisible by 3.

Hence, the correct answer is "625".

Given:

M > N ≤ D = S < F > I < U 

Option (1). F > N (True, as N ≤ D = S < F is given in the series, This is definitely true)

Option (2). S < U (False, as S < F > I < U is given in the series, in which > and < both the symbol has been used. So, there is no definite relation can be found in between S and U).

Option (3). M > S (False, as M > N ≤ D = S is given in the series, in which > and < both the symbol has been used. So, there is no definite relation can be found in between M and S).

Option (4). F > M (False, M > N ≤ D = S < F is given in the series, in which > and < both the symbol has been used. So, there is no definite relation can be found in between M and F).

Hence, the correct answer is "F > N".

Hence, there are two pairs possible in the word "NORM".

According to the given conditions, 

Six persons A, B, C, D, E and F are sitting in a row facing North.

• B sits to the left of D who sits to the immediate right of E.

• F sits to the immediate left of C who sits to the right of D.

Option2: E sits third to the left of C. (correct)

Option3: A is sitting fifth to the right of F. (not correct - as A sits fourth to the left of F)

Option4: F is sitting fifth to the right of B. (not correct - as F sits third to the right of B)

Hence, the correct answer is "E sits third to the left of C".

Given:

The loss incurred by selling an article for Rs. 11596 is equal to the profit incurred when the same article is sold for Rs. 16040.

Formula used:

Loss = cost price - selling price

Profit = selling price - cost price

Selling price = cost price × $\dfrac{100+profit \ percentage}{100}$

Calculations:

Let the profit earned when an article is sold for Rs. 16040 be x.

So, cost price of an article = 16040 - x (eqn1)

According to the problem,

The loss earned when an article is sold for Rs. 11596 be x.

Cost price of an article = 11596 + x (eqn2)

From eqn1 and eqn2,

16040 - x = 11596 + x

2x = 4444

x = 2222

From eqn1,

Cost price of an article = 16040 - 2222

= Rs. 13818

Now, the selling price of an article when profit is 50%.

Selling price = 13818 × (100 + 50%)/100

= 13818 × $\dfrac{150}{100 × 100}$

= $\dfrac{2072700}{100}$

= Rs. 20727

The answer is Rs. 20727.

The logic follows here is,

(first number) - (second number)

The digits of the first number are interchanged and then divided by 2 gives the second number.

1) 84 - 24

→ 48 ÷ 2 = 24 = Second number.

2) 21 - 6

→ 12 ÷ 2 = 6 = Second number.

3) 42 - 12

→ 24 ÷ 2 = 12 = Second number.

4) 46 - 16

→ 64 ÷ 2 = 32 ≠ 16

Hence, the correct answer is "46 - 16".

The logic follows here is:

The sum of the positional value of the first letter and the number is equal to the positional value of the second letter.

1. E3H

2) D1f

3. A3D

4. F9O

Thus, the odd term is 'D1F'.

Hence, the correct answer is "D1F".

On folding the cube, the following faces are opposite to each other:

1. 1 is opposite to 3.
2. 2 is opposite to 4.
3. 5 is opposite to 6.

As we know, no two opposite surfaces are adjacent to each other.

Option 1: No opposite surfaces are adjacent to each other.

So, the cube in option 1 can be based on the given unfolded cube in the question figure.

Option 2: No opposite surfaces are adjacent to each other.

So, the cube in option 2 can be based on the given unfolded cube in the question figure.

Option 3: No opposite surfaces are adjacent to each other.

So, the cube in option 3 can be based on the given unfolded cube in the question figure.

Option 4: 1 and 3 are adjacent to each other.

So, the cube in option 4 cannot be based on the given unfolded cube in the question figure, as two opposite sides are adjacent to each other.

Hence, the correct answer is "option 4".

The logic follows here is :

Given: 0, -6, -24, -65, -120, -210

1 - (1)³  = 1 - 1 = 0

2 - (2)³ = 2 - 8 = -6

3 - (3)3 = 3 - 27 = -24

4 - (4)3 = 4 - 64 = -60 ≠ -65

5 - (5)3 = 5 - 125 = -120

6 - (6)3 = 6 - 216 = -210

Thus, the wrong term is '-65'.

Hence, the correct answer is "-65".

Given:

12 mm of 18 cm

Concept used: 

1 cm = 10 mm

Calculation:

⇒ 18 cm = 18 × 10 = 180 mm

Required Percentage = $\dfrac{12}{180 }$ × 100

⇒ 6.67%

∴  12 mm is 6.67% of 18 cm.

Concept used: 

Quotient = Dividend / Divisor + Remainder

Calculation:

The largest 4-digit number is 9999.

The biggest 4-digit number divisible by 16 = 9984

⇒ Quotient = 9984/28 = 356 + remainder

∴ The quotient is 356.

Given:

SP = Rs. 279

Loss% = 10%

Concept used: 

CP = $\dfrac{SP}{(1 - {Loss\% \over 100})}$

Gain% = $\dfrac{Gain}{CP}$ × 100

Calculation:

⇒ CP = $\dfrac{279}{(1 - {10\% \over 100})}$

⇒ CP = $\dfrac{279}{0.9}$ = Rs. 310

⇒ Gain = Rs. 372 - 310 = Rs. 62

⇒ Gain% = $\dfrac{62}{310}$ × 100

⇒ Gain% = 20%

∴ The Gain% is 20%.

Given:

The sum of cube of 3 numbers that are in the ratio 4 ∶ 5 ∶ 6 is 50625

Calculation:

Let, the three numbers be 4m, 5m and 6m.

According to the question,

⇒ (4m)³ + (5m)³ + (6m)³ = 50625

⇒ (64 + 125 + 216)m³ = 50625

⇒ m³ = $\dfrac{50625}{405}$

⇒ m³ = 125

⇒ m = 5

⇒ 4m = 20

⇒ 5m = 25

⇒ 6m = 30

∴ The numbers are 20, 25, 30.

Given:

30% of a number is 12 more than 1/6 th of that number.

Calculation:

Let, the number be m.

According to the question,

⇒ 30% × m = 12 + $\dfrac{1}{6}$ × m

⇒ 0.3m = 12 + $\dfrac{m}{6}$

⇒ 1.8m = 72 + m

⇒ 0.8m = 72

⇒ m = 90

∴ The number is 90.

Given:

The given numbers are 15, 24, 30.

Concept used: 

The smallest 4 digit number is 1000

The least common multiple (LCM) of two or more numbers is the smallest number that is a multiple of all of the numbers.

Calculation:

⇒ LCM(15, 24, 30) = 2 × 2 × 2 × 3 × 5 = 120

When we divide 1000 by 120, we get 40 as remainder.

⇒The smallest 4 digit number when divided by 15, 24, 30 leaves a common remainder 9 = 1000 - 40 + 120 + 9 =  1089

Since 1089 is not available in the option, we again add 120,

⇒ 1089 + 120 = 1209

∴ The smallest 4 digit number when divided by 15, 24, 30 leaves a common remainder 9 is 1209.

Given:

There are three numbers given: 27, 42, 57

Concept used: 

HCF of two or more numbers is the largest number that can divide each of the numbers without leaving a remainder.

Calculation:

⇒ HCF of (27 - 10), (42 - 8) and (57 - 6)

⇒ HCF(17, 34, 51) = 17

∴ The largest number is 17.

Given:

11 people went on a lunch together to a hotel.

The expenses for 10 of them is Rs. 400 each.

The expense of 10^th person is Rs 100 more than the average of all the 11 people.

Concept used: 

Average = Sum of observation / Number of observations

Calculation:

⇒ Sum of the expense of 10 persons = 400 × 10 = Rs. 4000

According to the question,

⇒ m = $\dfrac{4000 + m + 100}{11}$

⇒ 11m = 4100 + m

⇒ 10m = 4100

⇒ m = 410

The expense of 11^th person = m + 100 = Rs. 510

∴ The expense of 11^th person is Rs. 510.

Given:

The ratio of students to teachers are 16 ∶ 1

Calculation:

Let, the number of teachers be m.

According to the question,

⇒ $\dfrac{16}{1} = \dfrac{112}{m}$

⇒ m = 7

∴ The number of teachers required for the trip is 7.

Given:

There are 3 numbers.

If the second number is 7 times the third number and second number is twice first number.

The average of 3 numbers is 23 .

Concept used: 

Average = Sum of observation / Number of observations

Calculation:

Let, the three numbers be m, n & s.

⇒ $\dfrac{m + n + s}{3}$ = 23

⇒ m + n + s = 69

According to the question,

n = 7 × s = 2 × m

⇒ m = 3.5s

⇒ 3.5s + 7s + s = 69

⇒ 11.5s = 69

⇒ s = 6

⇒ m = 21

⇒ n = 42

∴ The smallest number is 6.

Given:

A train is 135 m long.

The speed of the train is 45 kmph.

Concept used: 

Distance = Speed × Time

1 km = 1000 m

1 hour = 60 minutes

1 minute = 60 seconds

Calculation:

⇒ Time = $\dfrac{135}{45} \times \dfrac{60\times60}{1000}$

⇒ Time = 10.8 seconds

∴ The time taken by train to pass the pole is 10.8 seconds.

Concept used: 

Successive Discounts = D1 + D2 - $\dfrac{D1\times D2}{100}$

Calculation:

For 16% and 20%,

⇒ Successive discount = 16 + 20 - $\dfrac{16\times 20}{100}$

⇒ 36 - 3.2 = 32.8%

For 16%, 20%, and 24%,

⇒ Successive discount = 32.8 + 24 - $\dfrac{32.8 \times 24}{100}$ 

⇒ 56.8 - 7.872 = 48.93%

∴ A single equivalent discount is 48.93%.

Given:

A sphere of diameter 18 cm is drawn into a wire of 1 cm radius.

Concept used: 

The volume of the sphere = $4\over 3$πr³

The volume of the cylinder = πr²h 

Calculation: 

The volume will remain the same.

⇒ $\dfrac{4}{3}$πr³ = πr²h

⇒ $\dfrac{4}{3}$ × 9³ = 1² × h

⇒ 4 × 3 × 81 = h

⇒ h = 972 cm

∴ The length of the wire is 972 cm.

Given:

SI = Rs. 80100 

CI = Rs. 81902.25

Time = 2 years

Concept used: 

SI = PRT/100

Calculation:

Simple interest for 2 years = 80100

⇒ Simple interest for 1 year = 80100/2 = 40050

Difference between CI and SI = 81902.25 - 80100 = 1802.25

⇒ Interest Rate = $\dfrac{1802.25}{40050} \times 100$ = 4.5%

On putting the value of SI, R and T in the formula of simple interest of 1 year,

⇒ 40050 = $\dfrac{P\times4.5\times1}{100}$

⇒ P = $\dfrac{4005000}{4.5}$ = Rs. 890000

∴ The sum of the money is Rs. 8,90,000.

Concept used: 

Average = Sum of observation / Number of observations

Calculation:

Total number of maths students = 300 + 288 + 303 = 891

Total number of schools = 3

⇒ Average = $\dfrac{891}{3}$ = 297

∴ The average number of students in maths is 297.

Given:

p/q = 7/4

Calculation:

Let, p = 7m and q = 4m for some value m.

⇒ $\dfrac{p^2-q^2}{p^2+q^2} = \dfrac{(7m)^2-(4m)^2}{(7m)^2+(4m)^2}$

⇒ $\dfrac{49m^2 - 16m^2}{49m^2+16m^2}$

⇒ $\dfrac{33m^2}{65m^2}$

⇒ $\dfrac{33}{65}$ = 0.51

∴ The required value is 0.51

Given:

2.0006, 4.0088

Concept used: 

To convert any terminating decimal number into a fraction, divide the number after removing the decimal by 10 to the power m, where m is the number of digits after the decimal.

Calculation:

⇒ 2.0006 = $\dfrac{20006}{10000}$ = $\dfrac{10003}{5000}$

⇒ 4.0088 = $\dfrac{40088}{10000}$ = $\dfrac{5011}{1250}$

∴ 2.0006, 4.0088 in fractional form is 10003/5000, 5011/1250.

Given:

Suresh = 9 days

Nimesh = 18 days

Calculation:

Work done by Nimesh in 1 day = $\dfrac{1}{18}$ units

Work done by Suresh in 1 day = $\dfrac{1}{9}$ units

⇒ Work done by both in 1 day = $\dfrac{1}{18} + \dfrac{1}{9}$ = $\dfrac{1}{6}$ units

⇒ Work done in 4 days by both = 4 × $\dfrac{1}{6}$ = $\dfrac{2}{3}$ units

$x = {-b \pm \sqrt{b^2-4ac} \over 2a}$

⇒ Work left to be done = 1 - $\dfrac{2}{3} = \dfrac{1}{3}$ units

Time taken by Nimesh to finish the left work = $\dfrac{18}{3}$ = 6 days

∴ Time taken by Nimesh to complete the work is 6 days.

Given:

A man sold two tables for Rs. 55450 each. On one he gains 18% and on the other he loses 18%.

Concept used: 

Loss = CP - SP

Loss% = Loss/CP x 100

Calculation:

⇒ Total SP = 55450 × 2 = 110900

CP of first table = 55450 × $\dfrac{100}{118}$ = 46991.52

CP of second table = 55450 × $\dfrac{100}{82}$ = 67621.95

Total CP = 46991.52 + 67621.95 = 114613.47

⇒ Loss = 114613.47 - 110900 = 3713.47

Loss% = $\dfrac{3713.47}{114613.47} \times 100$ = 3.24%

∴ The Loss% is 3.24%.

Calculation:

Difference of Production in India = 840 - 754 = 86

⇒ Change in Production = $\dfrac{86}{754} \times 100$ = 11.4%

Difference of Production in China = 848 - 736 = 112

⇒ Change in Production = $\dfrac{112}{736} \times$ 100 = 15.2%

Difference of Production in Nepal = 834 - 744 = 90

⇒ Change in Production = $\dfrac{90}{744} \times$ 100 = 12.09%

Difference of Production in Pakistan = 774 - 770 = 4

⇒ Change in Production = $\dfrac{4}{770} \times$ 100 = 0.519%

Difference of Production in Sri Lanka = 838 - 744 = 94

⇒ Change in Production = $\dfrac{94}{744} \times$ 100 =12.63%

∴ In 1 country the production of cars has increased by less than 10% in the year 2020 over the last year.

The correct answer is "incomprehensive".

Key Points

• In the above question we have to choose the most appropriate word to fill in the blanks**.**
• The word "incomprehensive" means difficult to understand, which is an appropriate way to describe productions that are manifestly crazy.
• The use of the word "incomprehensive" emphasizes that the productions are so strange and unusual that they are difficult to comprehend.
• In this sentence, the speaker is describing a group of people who offered productions that were "incomprehensive" and "manifestly crazy."
• The use of "incomprehensive" to describe the productions emphasizes their difficult-to-understand nature, while the use of "manifestly crazy" emphasizes their absurdity. The use of "amazed contemporaries" implies that these productions were not only unusual but also striking and captivating to the audience.
• Thus, as per the above explanation, the most appropriate word is "incomprehensive"

Correct Sentence: They offered incomprehensive and manifestly crazy productions to their amazed contemporaries.

Additional Information

• "Moony" means dreamy or fanciful.
• "Lackadaisical" means lazy or apathetic, which does not match the tone of the sentence.
• "Inert" means lacking in energy or movement, which is not appropriate to describe productions that are "manifestly crazy."

The correct answer is "​the Principle of Priority, which states; you must".

Key Points

• The word "Principal" is correctly replaced with "Principle" as "Principal" refers to the head of a school or organization, whereas "Principle" refers to a fundamental truth or rule.
• The word "which" is used to introduce a non-restrictive clause which gives additional information about the Principle of Priority, it also replaces "that" which is less formal and more appropriate for the context.
• "you must" is used to indicate that it is an imperative statement and it is necessary to know the difference between what is urgent and important and do the important things first.
• Thus, the correct sentence would be, "I'm keenly aware of the Principle of Priority, which states you must know the difference between what is urgent and what is important, and, you must do what's important first.

Correct Sentence: I'm keenly aware of the Principle of Priority, which states you must know the difference between what is urgent and what is important, and, you must do what's important first.

The correct answer is "​necessarily spreading over a period of many years- will public".

Key Points

• The error in the part of the sentence is that the word "if" and "necessarily" are not correctly used.
• "if" is used to introduce a condition and "necessarily" means "in a necessary manner" both don't make sense in the context of the sentence. It is likely that the writer intended to use a different conjunction or adverb.
• To fix this error we have to remove the word "necessarily" from this part and use "Spread" instead of "Spreading"

Correct Sentence: Only after such preparatory measures-if spread over a period of many years will public attention and public resolution be fully aroused.

The correct answer is "RECESSION"

Key Points

• The correctly spelt word is "RECESSION".
• A recession is a period of economic decline, typically characterized by a reduction in gross domestic product (GDP), increased unemployment, and a decline in the stock market. During a recession, consumer and business spending decreases, and this reduction in spending can cause businesses to lay off workers and reduce production.(मंदी)
• For example, the 2008 global financial crisis and the following recession is one of the most significant examples of a recession in recent history. It was caused by the collapse of the housing market and the resulting decline in consumer spending. The crisis led to a significant decrease in GDP and a sharp increase in unemployment, with millions of people losing their jobs. The stock market also experienced a significant decline, with many investors losing a significant amount of money.
• Thus, the correct spelling is "RECESSION".

Correct answer: RECESSION

The correct answer is "Torrent"

Key Points

• A torrent refers to a strong, fast-moving flow of water or other fluid, such as a stream or river that is flowing rapidly and forcefully, often as a result of heavy rain or melting snow.

• For example, During a heavy rainstorm, a small stream might turn into a raging torrent, overflowing its banks and flooding nearby homes and businesses. Or during the melt of heavy snow, a mountain stream may turn into a massive torrent that causes damage to the infrastructure and communities downstream.
• Thus, the most appropriate meaning of the word "Torrent" is "A violent or forceful flow of fluid."

Correct answer: A violent or forceful flow of fluid.

The correct answer is "​SPQR".

Key Points

• The correct sequence is "SPQR"
• The first part should be that best connects the opening of the paragraph**.**
• S will be the next part after starting as it best connects the opening, this sentence provides the background for the creation of the Grammys, explaining that the committee realized that many important people in the recording industry would not be honored with a star on Hollywood Boulevard.
• P follows S, because this sentence explains that the recording executives decided to create an award to honor people in their industry, similar to the Oscars and the Emmys.
• Q follows P, because this sentence states that after deciding to create the awards, the question of what to name them remained.
• R follows Q because because it best connects the previous sentence and explain what question is remained, and, also it best connects the last given sentence.

Correct arrangement:   The Grammys had their origin in the Hollywood Walk of Fame project in the 1950s. As recording executives on the Walk of Fame committee compiled a list of significant recording industry people who might qualify for a Walk of Fame star, they realized that many leading people in their business would not earn a star on Hollywood Boulevard.They determined to rectify this by creating awards given by their industry similar to the Oscars and the Emmys. After deciding to go forward with such awards, a question remained what to call them. One working title was the 'Eddie', to honour Thomas Edison, the invent or of the phonograph. Eventually, the name was chosen after a mail-in contest whereby approximately 300 contestants submitted the name 'Grammy', with the earliest post mark from contest winner Jay Danna of New Orleans, Louisiana, as an abbreviated reference to the gramophone.

The correct answer is "​The first preliminary criteria to be fulfilled before".

Key Points

• The error lies in the part "The first preliminary criteria to be fulfilled before".
• The sentence is using "criteria" which is a plural noun, but it is being used with "the first" which is singular. So it should be "The first preliminary criterion" instead of "The first preliminary criteria".
• Thus, it should be criterion instead of criteria.

Correct Sentence: The first preliminary criterion to be fulfilled before the state can claim the moral right to fight against all these things is that the young generation should be afforded facilities for contracting an early marriage.

THe correct answer is "the metrics by which we measure".

Key Points

• The word segment that substitutes the bracketed word segment correctly and completes the sentence meaningfully is 'the metrics by which we measure'
• Because "by which" indicates the means by which something is done, or the standard by which something is judged or measured, and it makes sense in the context of the sentence.
• Thus, the most appropriate substitution is "the metrics by which we measure".

Correct Sentence: Our values determine the metrics by which we measure ourselves and everyone else."

The correct answer is "​INGENUOUS".

Key Points

• In the given question, we have to choose the word that is opposite to the meaning of the word "HYPOCRITE".

दिए गए सभी विकल्पों में सही उत्तर ' सहर्ष' है। 

Key Points

• सहर्ष : स + हर्ष
• स : उपसर्ग
• हर्ष : मूल शब्द
• व्याख्या : उपसर्ग वे शब्दांश होते है, जो किसी शब्द के शुरु में लगते हैं। उपसर्ग उस शब्द के आगे लगकर एक तरह से विशेषण का कार्य करते हैं। उपसर्ग लगते ही उस शब्द या तो अर्थ बदल जाता है, या उस शब्द का अर्थ और अधिक विस्तृत हो जाता है।

उपसर्ग को अंग्रेजी में प्रिफिक्स (Prefix) कहते हैं

• आ, वि, ना, स उपसर्ग से दो-दो शब्द बनाइए।
• उ���्तर: आ-आजन्म, आकाश वि-विनय, विजयना-नाराज, नादानस–सहर्ष, सहित।

Additional Information

• उपसर्ग
• जो शब्दांश किसी मूल शब्द के पहले जुड़कर उसके अर्थ मेँ परिवर्तन या विशेषता उत्पन्न कर देते हैँ, उन शब्दांशोँ को उपसर्ग कहते हैँ। जैसे –
• ‘हार’ एक शब्द है। इस शब्द के पहले यदि 'सम्, वि, प्र', उपसर्ग जोड़ दये जायेँ, तो– सम्+हार = संहार, वि+हार = विहार, प्र+हार = प्रहार तथा उप+हार = उपहार शब्द बनेँगे। यहाँ उपसर्ग जुड़कर बने सभी शब्दोँ का अर्थ ‘हार’ शब्द से भिन्न है।
• उपसर्गों का अपना स्वतंत्र अर्थ नही होता, मूल शब्द के साथ जुड़कर ये नया अर्थ देते हैँ। इनका स्वतंत्र प्रयोग नहीँ होता। जब किसी मूल शब्द के साथ कोई उपसर्ग जुड़ता है तो उनमेँ संधि के नियम भी लागू होते हैँ। संस्कृत उपसर्गोँ का अर्थ कहीँ–कहीँ नहीँ भी निकलता है। जैसे – ‘आरम्भ’ का अर्थ है– शुरुआत। इसमेँ ‘प्र’ उपसर्ग जोड़ने पर नया शब्द ‘प्रारम्भ’ बनता है जिसका अर्थ भी ‘शुरुआत’ ही निकलता है।
