Reasoning PYQs

Given: Seven people, R, S, T, U, V, W and X are sitting in a row facing east.

V is seated third from the right end.

S is fourth to the left of W.

R is seated to the right of V and at one of the ends.

Only one person is seated between T and S.

U does not sit at any of the extreme ends.

Extreme left end = position 1 = X

Hence, the correct answer is Option 2.

The logic followed here is:

For, BDBF → JLJN

For, HJHL → PRPT

Now, apply the same to RTRV:

So, RTRV → ZBZD

Hence, the correct answer is Option 1.

The logic followed here is:

Given:

Ramesh starts from Point A (0, 0)

51 km North

Right turn → 55 km East

Right turn → 54 km South

Right turn → 56 km West

Right turn → 3 km North

So, To return to Point A, Ramesh must move 1 km East.

Hence, the correct answer is Option 4.

Given

Statements:

All hydrogen is oxygen.

Some oxygen is nitrogen.

Some nitrogen is carbon.

The least possible Venn diagram for the given statement is:

Conclusions:

I. Some nitrogen is hydrogen – Does not follow  (There is no definite connection or overlap given between nitrogen and hydrogen, so this cannot be concluded.)

II. No carbon is oxygen – Does not follow (There is no stated restriction between carbon and oxygen, so we cannot conclude they are completely separate.)

So, neither conclusion I nor II follows.

Hence, the correct answer is "Option 1".

The logic followed here is:

Given number: 1368497

Original number: 1 3 6 8 4 9 7

Digits arranged in ascending order: 1 3 4 6 7 8 9

→ Second digit from the left = 3

→ Second digit from the right = 8

Sum = 3 + 8 = 11

Hence, the correct answer is Option 2.

Given: (Left) 9 1 7 9 7 3 1 9 1 7 7 5 (Right)

Now,

Odd digits, which are immediately preceded by an odd digit and also immediately followed by an odd digit.

So, Needed pattern is: Odd - Odd - Odd

(Left) 9 1 7 9 7 3 1 9 1 7 7 5 (Right)

So, total valid odd digits = 8

Hence, the correct answer is Option 1.

The logic followed here is:

For, CUV : AYT

For, YCR : WGP

Now, check the options using the same pattern:

Option 1) UKN : SOL

Option 2) KGX : HKU

Option 3) ANP : VRK

Option 4) TWG : PYC

Hence, the correct answer is Option 1.

The logic followed here is:

Given number: 9214538

Original number: 9 2 1 4 5 3 8

Digits arranged in ascending order: 1 2 3 4 5 8 9

Digits with unchanged positions = 2, 4, 5

Total unchanged digits = 3

Hence, the correct answer is Option 1.

The logic followed here is:

Logic: third number = (first number × second number) × 3

For, (28, 4, 336)

⇒ 28 × 4 = 112

⇒ 112 × 3 = 336

For, (25, 5, 375)

⇒ 25 × 5 = 125

⇒ 125 × 3 = 375

Now, checking the options using the same pattern:

Option 1) (26, 6, 368)

⇒ 26 × 6 = 156

⇒ 156 × 3 = 468 ≠ 368

Option 2) (41, 3, 379)

⇒ 41 × 3 = 123

⇒ 123 × 3 = 369 ≠ 379

Option 3) (32, 3, 288)

⇒ 32 × 3 = 96

⇒ 96 × 3 = 288

Option 4) (31, 6, 465)

⇒ 31 × 6 = 186

⇒ 186 × 3 = 558 ≠ 465

Hence, the correct answer is Option 3.

The logic followed here is:

thus, "18" will replace the question mark in the given series.

Hence, the correct option is "Option 2".

Given:

‘give me bike’ is written as ‘bn gt ry’

‘who know me’ is coded as ‘ry fh vt’

So, me = ry

Hence, the correct answer is Option 3.

Given: A, B, C, D, N, O and P are sitting in a straight line facing north.

Only N sits to the left of P.

Only four people sit between N and A.

Only B sits between O and C, and O is not an immediate neighbour of A.

Extreme right end = position 7 = D

Hence, the correct answer is Option 2.

The logic followed here is based on the alphabetical position pattern:

Option 1: SO – NJ

Option 2: TP – OK

Option 3: NJ – HG

Option 4: JF – EA

Thus, NJ – HG is different from the rest given options.

Hence, the odd one out is Option 3.

Given: (Left) $ # # £ 9 % £ 7 * & € 1 3 4 5 6 4 9 € 2 5 & (Right)

Now,

Numbers, which are immediately preceded by a symbol and also immediately followed by a symbol.

So, Needed pattern is: Symbol - Number - Symbol

(Left) $ # # £ 9 % **£ 7 *** & € 1 3 4 5 6 4 9 € 2 5 & (Right)

So, total valid numbers = 2

Hence, the correct answer is Option 1.

Shortcut Trick

The sequence follows a pattern of constant subtraction.

249 − 232 = 17

232 − 215 = 17

The pattern is to subtract 17 from the previous number.

Next number = 181 − 17 = 164.

∴ The correct answer is 164.

Alternate Method

Given series: 249, 232, 215, 198, 181, ?

249

−17
→

232

−17
→

215

−17
→

198

−17
→

181

−17
→

164

The series is an Arithmetic Progression where each successive term is obtained by subtracting a fixed number (17).

⇒ 249 − 17 = 232

⇒ 232 − 17 = 215

⇒ 215 − 17 = 198

⇒ 198 − 17 = 181

⇒ 181 − 17 = 164

∴ The correct answer is 164.

Additional Information

Arithmetic Progression (AP)

A sequence of numbers in which the difference between any two consecutive terms is constant, known as the common difference (d).

General Term of AP

The n^th term of an AP is given by a_n = a + (n − 1)d, where 'a' is the first term and 'd' is the common difference.

Common Difference Formula

The common difference can be calculated as d = a_n − a_n−1. In this series, d = 232 − 249 = −17.

Given

Statements:

Some houses are kites.

All mangoes are houses.

All flowers are kites.

The least possible Venn diagram for the given statement is:

Conclusions:

I. Some houses are flowers – Does not follow (Flowers are inside kites, and houses only partially overlap with kites.)

II. No flowers are mangoes – Does not follow (Flowers are inside kites and mangoes are inside houses, but there is no fixed restriction between flowers and mangoes.) 

So, neither conclusion I nor II follows.

Hence, the correct answer is "Option 3".

The logic followed here is based on the alphabetical position pattern:

Option 1: QPT

Option 2: ORN

Option 3: KNJ

Option 4: FIE

Thus, ORN, KNJ and FIE follow the same (+3, −4) positional pattern, while QPT follows a different pattern.

Hence, the odd one out is Option 1.

Given: Six people, A, B, C, D, E and F, are sitting in a row facing north.

A sits to the immediate right of E.

B sits fourth to the left of E.

Only one person sits between B and F.

C sits immediately to the left of F.

D sits second to the left of A.

Three pairs (CF, FD, DE) are adjacent consecutive neighbors, while BA is not.

Hence, the correct answer is Option 4 (BA).

Given:

‘bring the cup’ is coded as ‘bz rs tq’

‘cup on the’ is coded as ‘rs pl tq’

So,

the → rs / tq

cup → rs / tq

Remaining word = on

Remaining code = pl

So, on = pl

Hence, the correct answer is Option 4.

Family Chart:

Decoding the Symbols:

Given: F × G + H − I ÷ K

It means: F is the wife of G, G is the father of H, H is the husband of I, and I is the mother of K.

Hence, F is Father's mother.

Therefore, the correct answer is Option 1.
