Reasoning PYQs

Preparing the family tree diagram by using the following symbols:

Let us first decode the given symbols and then draw a family tree.

 

Given expression: S ÷ D & R # Y + H’

Based on the family tree, S is the brother of R, R is the wife of Y, and Y is the brother of H. Thus, S is the brother of H's brother's wife.

Therefore, S is the Brother's wife's brother of H.

Hence, the correct answer is 'Option 1'.

The logic follows here, 

Hence, the correct answer is "option 2"

BODMAS Table:

Sign Conversion:

 

Given:  38 − 25 ÷ 133 + 703 × 19

After replacing the symbols with their meaning and following BODMAS rule, we get.

= 38 × 25 + 133 − 703 ÷ 19

= 38 × 25 + 133 − 37

= 950 + 133 − 37

= 1083 − 37

= 1046

Hence, the correct answer is "option 3"

Given word**: COMBINE:**

Only the letter N remains in its original 6^th position after the letters are arranged in alphabetical order.

The number of letters whose position remains unchanged is 1.

Hence, the correct answer is "option 3"

The logic followed here is,

• 486 − 45 = 441
• 441 − 40 = 401
• 401 − 35 = 366
• 366 − 30 = 336
• 336 − 25 = 311

 

Thus, the missing term in the series is 311.

Hence, the correct answer is 'Option 1';

The logic followed here is:

Total number of people in the row = 195

Position of Rt from the left end = 143^rd

Position of Kl from the right end = 36^th

To find the number of people between them, we first determine the position of Kl from the left end.

Position of Kl from the left end = (Total number of people − Position of Kl from the right end) + 1

= (195 − 36) + 1

= 159 + 1

= 160^th

Now, the number of people between Rt and Kl = (Position of Kl from the left end − Position of Rt from the left end) − 1

= (160 − 143) − 1

= 17 − 1

= 16

Hence, the correct answer is "Option 3".

Given word:  VOLUNTARY

Applying the logic to the word VOLUNTARY:

The letters formed after the transformation are: U, Q, K, W, M, S, C, Q, X.

The letter Q appears exactly twice in the group.

Hence, the correct answer is "option 1"

The least possible Venn diagram for the given statements is:

(I) All buttons are kings - Doesn't follow (All kings are buttons and All buttons are kings is may be possible but not definite.Hence, it is false)

(II) Some buttons are not pants - Follow (all kings are buttons and no kings are pants, the part of buttons that consists of kings can never be pants.)

Only conclusion (II) follows

Hence, the correct answer is " Option 2"

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

1. Q is placed at the topmost position.
2. Exactly three boxes are kept between P and M, and P is kept on one of the positions above M.
3. Box M is kept immediately above O.

1. Only one box is kept between R and O, and R is kept on one of the positions above O.
2. Box N is kept immediately below L.

Final Arrangement:

Thus, the box kept fourth from the top is N.

Hence, the correct answer is 'Option 1'.

Given : A, B, C, D, S, T and U are sitting around a circular table, facing the centre of the table.

1. Only three people sit between B and C, when counted from the left of B.
2. Only three people sit between U and T, when counted from the right of T.
3. D sits to the immediate right of U.
4. A is an immediate neighbor of T as well as C

 

The Final Arrangement is, 

 Therefore, A sits second to the left of S.

Hence, the correct answer is 'Option 2'.

The logic followed here is,

Logic: Second letter = First letter − 4; Third letter = Second letter + 2.

OLM,

 

CYA,

EAC,

AWY,

Therefore, the letter cluster that is different from the others is OLM.

Hence, the correct answer is 'Option 1'.

The logic follows here, 

KG 13 is related to IC −2,

NH 20 is related to LD 5,

Applying same logic to NW 24 is related to LS 9,

Hence, the correct answer is 'Option 3'.

Logic followed here is.

Logic: The second letter cluster is determined by subtracting 6 from the positional values of the letters in the first cluster.

For

QMO − KGI,

 

For RNP − LHJ,

Applying for the same logic, 

For KGI−EAC,

Hence, the correct answer is "Option 4"

Given: P W I C T G T X W J N L X T D X E S C S Z 

Required Pattern: Consonant — Vowel — Consonant

(Left) P W I C T G T X W J N L X T D X E S C S Z (Right)

I C , E S 

Hence, the correct answer is "option 4"

Given: Seven people, U, T, E, N, S, I and L, are sitting in a row, facing the north.

1. Only E sits to the left of N.
2. Only four people sit between E and T.
3. Only U sits between I and L and I is not an immediate neighbor of T.

The final seating arrangement,

From the above arrangement, we can see that S sits at the extreme right of the line.

Hence, the correct answer is "option 1"

The logic followed here is

For MN - CY,

For OP - EA,

For UV - KG,

For JK - WV

This pair does not follow the rule, as the difference in the second cluster is −1.

Therefore, the letter-cluster pair that is different from the others is JK - WV.

Hence, the correct answer is 'Option 4'.

The logic followed here is:

Logic: (First Number + Second Number) + 18 = Third Number

For the first set (2, 11, 31)

⇒ (2 + 11) + 18

⇒ 13 + 18 = 31.

For the second set (13, 10, 41)

⇒ (13 + 10) + 18

⇒ 23 + 18 = 41.

Applying the same logic to the set (6, 1, 25)

⇒ (6 + 1) + 18

⇒ 7 + 18 = 25.

Hence, the correct answer is 'Option 4'.

BODMAS Table:

Given equation: 9 − 4 + 45 × 5 ÷ 3 = ?

The operator conversions are:

 

After replacing the symbols with their new meanings, the equation becomes:

= 9 × 4 − 45 ÷ 5 + 3

= 9 × 4 − 9 + 3

= 36 + 3 − 9

= 39 − 9

= 30

The value that comes in place of the question mark is 30.

Hence, the correct answer is "option 4"

Preparing the family tree diagram by using the following symbols:

As per the given information

Let us first decode the given symbols and then draw a family tree.

Given : H − I + O * D * J

 

Therefore, D is the mother of J, and I is the mother of D (as I is the wife of D's father O). H is the brother of I. Thus, H is the Mother's mother's brother of J.

Hence, the correct answer is 'Option 3'.

BODMAS Table:

Given Interchanges:

• + and ÷ are interchanged.
• − and × are interchanged.

Given Equation: 14 − 2 × 48 + 3 ÷ 7 = ?

Step 1: Replace the signs with their interchanged and applying BODMAS rule, 

The new equation becomes: 14 × 2 − 48 ÷ 3 + 7

= 14 × 2 − 48 ÷ 3 + 7

= 14 × 2 − 16 + 7

= 28 + 7 − 16 

= 35 − 16 

= 19

The final value obtained is 19.

Hence, the correct answer is "option 2"
