Reasoning PYQs

Given: 2 is added to each odd digit and 2 is subtracted from each even digit in the number 6127385.

The new number formed is 3751864.

Sum of all the even digits in the new number thus formed: 8 + 6 + 4 = 14

Hence, the correct answer is "Option 3".

The logic followed here ,

Logic: (First letter − 3) = Second letter; (Second letter + 6) = Third letter.

Option 1) QNT:

Option 2) MJP:

Option 4) JGM:

Option 3) URY:

 

This letter-cluster does not follow the same rule as the others.

Therefore, the letter-cluster that is different from the others is URY.

Hence, the correct answer is 'Option 3'.

The logic followed here is:

Logic: First Number × Second Number = Third Number

In (8 - 3 - 24)

⇒ 8 × 3 = 24

In (5 - 8 - 40)

⇒ 5 × 8 = 40

Similarly,

4 - 9 - 36

⇒ 4 × 9 = 36

Here, in (4, 9, 36) similar logic is followed.

Hence, the correct answer is 'Option 4'.

Given: 

• Amit starts from Point Y and drives 14 km towards South.
• He then turns left and drives 35 km, takes a left and drives 68 km.
• He then takes a left turn and drives 41 km.
• He takes a left turn, drives 54 km, turns right and drives 53 km to stop at Point Z
• The final Diagram,

The shortest distance and the direction in which he should drive in order to reach Point Y again is = 53 km + 6 km = 59 km and in the east direction.

Hence, the correct answer is "Option 4".

The logic followed here is based on the positions of letters in the English alphabetical order.

Logic:

• Vowels (A, E, I, O, U) are replaced by the letter that is 2 positions ahead (+2).
• Consonants are replaced by the letter that is 2 positions behind (−2).

Applying the logic to the word TRAJECTORIES:

The new group of letters formed is: R, P, C, H, G, A, R, Q, P, K, G, Q

The letters that appear exactly twice are R, P, G, and Q are  4.

Hence, the correct answer is "Option 2".

The logic followed in this pattern is a consistent alphabetical shift of +5 for each letter in the sequence.

For 'AEHB' related to 'FJMG':

For 'DHKE' related to 'IMPJ':

Applying the same logic to 'GKNH':

Thus, GKNH is related to LPSM.

Hence, the correct answer is 'Option 3'.

The logic followed here is,

Therefore, the code for E is 8.

Hence, correct answer is option 2

Given:  603 + 9 × 18 − 6 ÷ 56 = ?

After ‘+’ and ‘÷’ are interchanged and ‘−’ and ‘×’ are interchanged and using the BODMAS rule,

603 ÷ 9 − 18 × 6 + 56 = ?

= 603 ÷ 9 − 18 × 6 + 56

= 67 − 18 × 6 + 56

= 67 + 56 − 108 

= 123 − 108 

= 15

Hence, the correct answer is "Option 1".

Given: Family Chart:

The family tree diagram is,

S is father of P and T is sister of S. T is the Father's sister of P.

Hence, the correct answer is 'Option 4'.

The logic followed here is:

Total number of students = (Rank from the top + Rank from the bottom) − 1

Given:

Rank of Uvx from the top = 14^th

Rank of Uvx from the bottom = 79^th

Total number of students = (Rank from the top + Rank from the bottom) − 1

= (14 + 79) − 1

= 93 − 1

= 92

Hence, the total number of students in the class is 92.

Hence, the correct answer is 'Option 2'.

According to the given Venn diagram:

The shaded area represents teachers are there who are also Dentists but not Surgeons are 29.

Hence, the correct answer is "Option 2".

The logic follows here,

Logic:  Each letter in the first group is shifted forward by 3 positions to form the second group

For 'DIP' related to 'GLS':

For 'BST' related to 'EVW':

Applying the same logic to the options:

Analyzing 'HKD' related to 'KNG':

The pair HKD : KNG perfectly follows the +3 shift pattern observed in the given sets.

Hence, the correct answer is 'Option 4'.

The logic follows here, 

Logic: The sequence of additions is: 3, 6, 9, 12, 15.

• 67 + 3 = 70
• 70 + 6 = 76
• 76 + 9 = 85
• 85 + 12 = 97
• 97 + 15 = 112

Therefore, the number that should come in place of the question mark is 76.

Hence, the correct answer is option 2

The logic followed here is:

Option 1) EH-JB

Option 2) OR-TM

Option 3) LO-QJ

Option 4) HK-MF

The letter-cluster that DOES NOT belong to the group is: EH-JB

Hence, the correct answer is "Option (1)"

Given number: 52178436

Arranging the digits of the number 52178436 in ascending order from left to right:

Left  1 2 3 4 5 6 7 8  Right

• Third from the left = 3
• Third from the right = 6
• The sum of these two digits is 3 + 6 = 9.

Hence, the correct answer is "Option 4".

Given : Seven people, N, V, C, Y, E, F and G, are sitting in a row, facing north.

1. Only two people sit to the left of V

2. Only two people sit between N and V

3. F sits fourth from the right end. 

4. E is the immediate neighbour of G and V.

5. Y does not sit to the right of C.

The final arrangement is,

Two people sit between Y and E: V and F

Hence, the correct answer is "Option 1."

The logic followed here is:

Logic: Alphabet (-1) and Number (-5)

So, 'CZD 46' will replace the question mark in the given series.

Hence, the correct answer is "Option 4".

Seven boxes, M, N, O, P, Q, R and S, are kept one over the other, but not necessarily in the same order.

1. No box is kept above O.
2. Only three boxes are kept between O and S.
3. M is kept immediately above S.
4. Only one box is kept between Q and M.
5. Only four boxes are kept between Q and P.
6. R is kept at some place above N.

The Final Arrangement is,

 

 

The box kept second below R (at position 5) is S (at position 3).

Hence, the correct answer is "Option 1".

The logic followed here is:

Logic: First Number × Second Number = Third Number

For the first set (2, 7, 14)

⇒ 2 × 7 = 14.

For the second set (3, 16, 48)

⇒ 3 × 16 = 48.

Similarly,

In Option 2: (5, 3, 15)

⇒ 5 × 3 = 15.

Hence, the correct answer is 'Option 2'.

The logic followed here is

Logic: The difference between the consecutive letters in each group is +2.

Option 1)  CEH

Option 2) PRT

Option 3) SUW

Option 4) HJL

Thus, out of all options "CEH" is the odd one out.

Hence, the correct answer is 'Option 1'.
