Statement:

Children are influenced more by their teachers.

1. A large amount of time is spent at school by the children → This is not implicit.

• Children of all ages do not go to school.
• For example, a 2-year old child does not go to school.
• Thus we cannot generalize that for all children, time spent in school is high.
• Also, the statement does not suggest anything about the time spent by children.

2. Children consider their teachers as role models → This is implicit.

• The word "influenced" used in the statement indicates that children are affected by their teachers. So, it is possible to assume that children prefer to follow their teachers more.
• Thus, teachers involuntarily become the role models of children.

Hence, option 1 is the correct answer.

EXPLANATION: 

1. B buys only one drink, which is a cold drink

2. Four of them each buy a cup of coffee.

3.B and D do not buy tea as all the others do

4. Only A and E do not buy ice-tea.

Clearly, C buy the three drinks.

Hence, the correct answer is "C".

The logic follows here is:-

Similarly,

Thus, the correct answer is “OSPHCB”.

Left Side: 1 P 3 5 2 Q A F G I 8 3 4 6 A D E 1 4 I U :Right Side

Odd numbers in this arrangement are :

1 P 3 5 2 Q A F G I 8 3 4 6 A D E 1 4 I U

After deleting the odd numbers, we get:

P 2 Q A F G I 8 4 6 A D E 4 I U 

Vowels in this arrangement are:

P 2 Q A F G I 8 4 6 A D E 4 I U 

After deleting the vowels, we get:

P 2 Q F G 8 4 6 D 4

The fifth element from the right end will be:

P 2 Q F G 8 4 6 D 4

Hence, "8" is the correct answer.

Odd numbers are whole numbers that cannot be divided exactly into pairs.

Odd numbers, when divided by 2, leave a remainder of 1. 1, 3, 5, 7, 9, 11, 13, 15,.. are sequential odd numbers. Odd numbers have the digits 1, 3, 5, 7, or 9 in their one's place.

Numbers that have only two factors namely 1 and the number itself are called prime numbers.

An odd number can be composite and prime too. An even number can be composite and prime.

Like 2 is an even number and prime number both. Likewise, 1 is an odd number.

The logic is:

62 - 3 = 33

72 + 4 = 53

8² - 3 = 61

9² + 4 = 85

102 - 3 = 97

112 + 4 = 125

12² - 3 = 141

Hence, ‘125’ is the correct answer.

The pattern followed here is:

Logic: [(First number × (First number ÷ 2)] × 3 = Second number.

1. 8 : 96

⇒ [(8 × (8 ÷ 2)] × 3 

⇒ [(8 × 4)] × 3

⇒ 32 × 3 = 96

And,

2. 12 : 216

⇒ [(12 × (12 ÷ 2)] × 3 

⇒ [(12 × 6)] × 3

⇒ 72 × 3 = 216

Similarly,

3. ? : 54

By option 6 is using.

⇒ [(6 × (6 ÷ 2)] × 3 

⇒ [(6 × 3)] × 3

⇒ 18 × 3 = 54

Hence, the correct answer is "6".

I. People who do not walk an hour a day are generally obese.

Statement mentions that walking an hour a day can help people to reduce weight which does not mean that people whose daily routine does not include walking are obese. So, I does not follow.

II. Walking is the best exercise for weight loss.

However, the statement talks about the role of walking in reducing weight but it can't be concluded that it is the best for weight loss. So, II does not follow.

Hence, neither conclusion I nor II follows.

The logic followed here is:

The sum of the positional value of the letters is a prime number.

Option (1) OPEA:

15 + 16 + 5 + 1

= 37

Option (2) BGNH:

2 + 7 + 14 + 8

= 31

Option (3) LJHN:

12 + 10 + 8 + 14

= 44

Option (4) KIMH:

11 + 9 + 13 + 8

= 41

Here the sum of the positional value of all the options except LJHN is prime numbers.

Hence, LJHN is the odd one out.

Given: Six friends A, B, C, D, E and F are sitting on a bench facing north.

(1): B is sitting at one extreme end of the bench. So, there have two possibilities

Case(I): 

Case (II):

(2): F is an immediate neighbour of both just D and B.

Case(I):

Case (II):

(3): A is sitting second to the right of C, who is an immediate neighbour of D. i.e. A is sitting second to the right of C and C is an immediate neighbour of D.

So, Case (II) is eliminated. 

Case (I):

Then, the final arrangement is:

Therefore, A is sitting at the other extreme end. 

Hence, the correct answer is A.

Here, we use the table given below:

​

Given:

PJVG, VBZB, BTDW, HLHR,?

The logic followed in the given series is as:

Here, the missing term is 'NDLM'.

Hence, the correct answer is "Option (3)".

For this question, we use the table given below-

According to the given information,

By using the symbols given in the above table we solve the expression, L * M @ N % O * P as-

L * M

L * M @ N 

L * M @ N % O

L * M @ N % O * P

From the above diagram, we can say that N is the daughter-in-law of P.

Hence, Option (2) is correct.

The given figure when unfolded is as follows:

Hence, this paper will look as the above figure when unfolded.

Hence, “option figure 3” is the correct answer.

Confusion Points

The pattern followed in given series is;

Here, '221' doesn't belong to the series, the correct series would be;

Hence, the correct answer "221".

Given: 16 June 2001 is Saturday.

Now,

16 June 2001 to 16 June 2009 = 8 Years (6 Ordinary Year and 2 Leap Year).

And, In 8 Years = 2 Leap years and 6 Ordinary Year.

So, 2 Leap Year has 4 odd days,

And, 6 Ordinary Year has 6 odd days.

Total odd days = 4 + 6 = 10.

10 odd days → 10/7 = 1 week and 3 odd days.

then, 16 June 2009 will be Saturday + 3 = Tuesday.

Now, the number of days between 16 June 2009 to 21 June 2009 = 5 days

So, 21 June 2009 will be Tuesday + 5 = Sunday.

Hence, the correct answer is "Option 3".

The pattern followed is:

Thus we can see here 62 is the wrong term.

The correct series is given below:

We can conclude that 62 must be replaced with 61.

Hence, the correct answer is "62".

EXPLANTION:

Hence "Amit" neither hardworking nor a scholar.

Given series: 58, 73, 99, 138, 193, ?, 368

The logic is:

Hence, ‘268’ is the correct answer.

Given:

Sum of five numbers = 655

Average of the first two numbers = 78

Third number = 103

Formula Used:

Average = Sum of numbers / Total numbers

Calculation:

Sum of the first two numbers = Average × Total numbers

Sum of the first two numbers = 78 × 2

⇒ Sum of the first two numbers = 156

Sum of the remaining two numbers = Total sum - (Sum of the first two numbers + Third number)

Sum of the remaining two numbers = 655 - (156 + 103)

⇒ Sum of the remaining two numbers = 655 - 259

⇒ Sum of the remaining two numbers = 396

Average of the remaining two numbers = Sum of the remaining two numbers / 2

Average of the remaining two numbers = 396 / 2

⇒ Average of the remaining two numbers = 198

The average of the remaining two numbers is 198.

Given:- 

Total share = 15000 

The ratio of E and F shares is 3 : 2

The ratio of F and G shares is 6 : 5

Calculation:- 

Total share = Rs. 15000

Ratio of E and F share is 3 : 2

The ratio of F and G share is 6 : 5

⇒ E/F = 3/2  and F/G = 6/5 

⇒ E/F = (3/2) × (3/3) and F/G = (6/5) 

⇒ E/F = 9/6 and F/G = 6/5 

⇒ E : F : G = 9 : 6 : 5

Let E's, F's, and G's share be 9x, 6x, 5x

⇒ 9x + 6x + 5x = 15000

⇒ 20x = 15000 

⇒ x = 750

F's share = 6 × 750= Rs 4500

∴ The required answer is 4500.

Given:

A can do the work in 10 days

B can do the work in 15 days

C can do the work in 20 days

Formula used:

Work done = Time taken × Efficiency

Time taken ∝ 1/Efficiency

Calculation:

1^st day work by A = 1/10

2^nd day work by B = 1/15

3^rd day work by  C = 1/20

Total work completed in 3 days

⇒ 1/10 + 1/15 + 1/20

⇒ (6 + 4 + 3)/60 = 13/60

Time taken to complete the work

⇒ 60/13

⇒ 4(8/13)

They finish the same work in 4(8/13) days.

Work done together in 1 day is:

⇒ 6 + 4 + 3 = 13

Total time required to complete the work ⇒ 60/13

⇒ \(4\frac{8}{13}\) days

⇒ Product = 1715

∴ The correct answer is 1715.

Additional Information

Fundamental Property of HCF and LCM

For any two positive integers a and b, the relationship is HCF(a, b) × LCM(a, b) = a × b.

HCF as a Factor

The HCF of any set of numbers is always a factor of their LCM.

Co-prime Numbers

For co-prime numbers, the HCF is always 1 and the LCM is the product of the numbers themselves.

Given,

2^nd term of AP = 17

11^th term of AP = 35

Formula:

T_n = a + (n – 1)d

Where, a = first term and d = common difference

Calculation:

T₂ = a + (n – 1) × d

⇒ 17 = a + d     ----(1)

T₁₁ = a + (n – 1) × d

⇒ 35 = a + 10d    ----(2)

Subtract equation (1) from equation (2)

18 = 9d

⇒ d = 18/9

⇒ d = 2

Putting d = 2 in equation (1), we get

17 = a + 2

⇒ a = 17 – 2

⇒ a = 15

∴ First term is 15.

Given:

∠ABC = ∠B = 50⁰

Calculation:

In the given figure ADCB is a cyclic quadrilateral.

In cyclic quadrilaterals sum of opposite angles is equal to 180⁰.

So,

∠B + ∠D = 180⁰

⇒ ∠D = ∠ADC = 180 - ∠B

⇒ ∠ADC = 180 - 50

⇒ ∠ADC = 130⁰

Hence, the correct answer is 1300.

Given:

Principal (P) = ₹ 7,81,250

Amount (A) = ₹ 9,13,952

Rate of interest (R) = 4% per annum

Time (T) = ?

Formula used:

Compound Interest formula:

A = P (1 + R/100)^T

Calculation:

Substituting the values:

9,13,952 = 7,81,250 (1 + 4/100)^T

9,13,952 = 7,81,250 × (1.04)^T

Dividing both sides by 7,81,250:

(1.04)^T = 9,13,952 / 7,81,250

(1.04)^T = 1.17

(1.04)T = (1.04)⁴

T = 4

The required time is 4 years.

Given:

The speed of a man traveling on a bicycle is 5 m/sec.

The speed of the train coming from behind is 50 m/sec which crosses him in 10 seconds.

The length of the platform is 550 m.

Formula Used:

Relative Speed = Distance/Time

Calculation:

Let the length of the train be L.

⇒ L = (50 – 5) × 10

⇒ L = 450 m

As speed of the train is 50 m/sec, then the time(T) taken by the train to cross the platform of length 550 m will be

⇒ (450 + 550) = (50) × T

⇒ T = 1000/50 = 20 sec

∴ The time taken by the train to cross the platform is 20 seconds.

⇒ 16

∴ The quantity of 1^st solution is 16 litres

Given:

In triangle ABC, DE∥BC

AD/DB = 3/5 and AC = 5.6 cm 

Concept used:

Basic Proportionality Theorem (BPT) = If line DE is parallel to side BC of triangle ABC that intersects the other sides into two points, line DE divides sides AB and AC in proportion.

AD/AB = AE/AC

Calculation:

In triangle ABC, AD/DB = 3/5

⇒ AD/AB = AE/AC = 3/(3 + 5) = 3/8 

⇒ AE/5.6 cm = 3/8 

⇒ AE = 5.6 × 3/8 

∴  AE = 2.1 cm

Given:

50 percent of a number is 392 more than 37.5 percent of the same number

Calculation:

Let the number be N

According to the question

N × (50/100) - N × (37.5/100) = 392

⇒ N × (12.5/100) = 392

⇒ N = 3136

∴ The required number is 3136.

Given: 

Numbers = 405, 648 & 486

Calculation:

LCM of 405, 648, and 486

405 = 3⁴ × 5

648 = 2³ × 3⁴

486 = 2 × 3⁵

LCM = 2³ × 3⁵ × 5 = 9720

Now, HCF of 405, 648 & 486 = 3⁴ = 81

LCM/HCF = 9720/81 = 120

Hence, the correct answer is 120.

Given:

Salary per month = Rs. 60,000

Fraction of salary spent on education = 1/4

Fraction of salary spent on food = 1/3

Formula Used:

Savings = Total Salary - (Amount spent on education + Amount spent on food)

Calculation:

Amount spent on education = 60,000 × (1/4)

⇒ Amount spent on education = 15,000

Amount spent on food = 60,000 × (1/3)

⇒ Amount spent on food = 20,000

Total amount spent = 15,000 + 20,000

⇒ Total amount spent = 35,000

Savings = 60,000 - 35,000

⇒ Savings = 25,000

The correct answer is option 4, Rs. 25,000.

Given:

The ratio of the salaries of Ravi and Sarita is 3 ∶ 5.

If the salary of each is increased by ₹ 5,000, the new ratio becomes 29 ∶ 45.

Formula Used:

Initial salaries: R = 3x and S = 5x.

New salaries: R + 5000 and S + 5000.

New ratio: (R + 5000) / (S + 5000) = 29/45.

Calculation:

Substituting the values of R and S in the new ratio equation:

(3x + 5000) / (5x + 5000) = 29 / 45

Cross multiplying to solve for x:

⇒ 45 × (3x + 5000) = 29 × (5x + 5000)

⇒ 135x + 225000 = 145x + 145000

⇒ 145x - 135x = 225000 - 145000

⇒ 10x = 80000

⇒ x = 8000

Now, finding the current salary of Sarita:

S = 5x = 5 × 8000

S = 40000

The present salary of Sarita is ₹ 40,000.
