Reasoning PYQs

From Statement I:

Straight line of 15 people

1. C stand fifth from the left end of the line, A and D are immediate neighbour of C.

2. Only two people stand between C and B.

As we can see in above diagram’s there are two cases so position of A and B is not definite hence, we can’t determine how many people are between A and B in straight-line of 15 people.

From Statement II:

Straight line of 15 people

1. E stands third from the right end of the line.

2. Only six people stand between D and E.

3. Only one person stands between A and D. D stand exactly between A and B.

4. D stand exactly between A and B.

From above diagram we can see that there are 3 people between A and B.

Hence, only statement II alone is sufficient to answer the question, while the data in statement I alone are not sufficient to answer the question.

Logic:

Step I: Add the digits of the number and multiply by 2.

Step II: Divide the number by 2 and square it.

Step III: Take Square root and add 12 in it

Step IV: Subtract the sum of digit from number

Step V: Add 2 in each number

Input:    52, 78, 43, 39, 47, 36, 57, 19

Step I:    14, 30, 14, 24, 22, 18, 24, 20

Step II:   49, 225, 49, 144, 121, 81, 144, 100

Step III: 19, 27, 19, 24, 23, 21, 24, 22

Step IV: 9, 18, 9, 18, 18, 18, 18, 18

Step V:   11, 20, 11, 20, 20, 20, 20, 20

Hence, “11, 20, 11, 20, 20, 20, 20, 20” will be fifth step of given input.

Logic:

Step I: Add the digits of number and multiply by 2.

Step II: Divide the number by 2 and square it.

Step III: Take Square root and add 12 in it

Step IV: Subtract the sum of digit from number

Step V: Add 2 in each number

Input: 13, 11, 19, 17, 24, 21, 27, 29

Step-1: 8, 4, 20, 16, 12, 6, 18, 22

Step-II: 16, 4, 100, 64, 36, 9, 81, 121

Hence 2^nd step of input will be “16, 4, 100, 64, 36, 9, 81, 121”

Logic:

Step I: Add the digits of number and multiply by 2.

Step II: Divide the number by 2 and square it.

Step III: Take Square root and add 12 in it

Step IV: Subtract the sum of digit from number

Step V: Add 2 in each number

Input 26, 29, 32, 35, 38, 41, 44, 47

Step-I: 16, 22, 10, 16, 22, 10, 16, 22

Step-II: 64, 121, 25, 64, 121, 25, 64, 121

Step-III: 20, 23, 17, 20, 23, 17, 20, 23

Hence, correct option is “20, 23, 17, 20, 23, 17, 20, 23”

Step I: Add the digits of number and multiply by 2.

Step II: Divide the number by 2 and square it.

Step III: Take Square root and add 12 in it

Step IV: Subtract the sum of digit from number

Step V: Add 2 in each number

Input: 9, 11, 7, 6, 13, 10, 12

Step I: 18, 4, 14, 12, 8, 2, 6

Step II: 81, 4, 49, 36, 16, 1, 9

Step III: 21, 14, 19, 18, 16, 13, 15  

Step IV: 18, 9, 9, 9, 9, 9, 9

Hence, fourth step of input will be “18, 9, 9, 9, 9, 9, 9”

Logic:

Step I: Add the digits of number and multiply by 2.

Step II: Divide the number by 2 and square it.

Step III: Take Square root and add 12 in it

Step IV: Subtract the sum of digit from number

Step V: Add 2 in each number

Given: Step-I: 8, 6, 16, 22, 12, 22, 18, 20

Step-II: 16, 9, 64, 121, 36, 121, 81, 100

Step-III: 16, 15, 20, 23, 18, 23, 21, 22

Step-IV:  9, 9, 18, 18, 9, 18, 18, 18

Step-V: 11, 11, 20, 20, 11, 20, 20, 20

Hence, “11, 11, 20, 20, 11, 20, 20, 20” will be correct option

Information given can be represented as,

As we can see from the third sentence,

N9 → not

T2 → truth

So, either of the remaining codes, i.e., F4 or S6, could be code for “perish”.

Information given can be represented as,

The common code between 4^th and 5^th sentence is “Z0” and the common word is “honesty”.

Thus word “honesty” has the code “Z0”.

Information given can be represented as,

Thus word “is” is coded as “S7”.

Information given can be represented as,

From these, we know

Enmity → E8

May → new code (should be present 2 times as the word “may” is coming for 2 times)

Perish → either F4 or S6

Or → new code

Not → N9

So the answer should have code E8, N9, either F4 or S6, a single new code and a double new code.

There is no such code present in the given options.
