Correct Answer is: Father

Given:

Harshit’s (Boy) mother's father's only son-in-law related to Harshit.

From the given information family diagram will be

So, Harshit’s (Boy) mother's father's only son-in-law related to Harshit as Father.

Thus, correct option is (a).

Correct Answer is: Grandson

Given: P is daughters of V and mother of S.

K is brother of S and son of A.

From the given information relationship diagram will be

K is grandson of V.​​

Thus, correct option is (a).

Correct Answer is: 98

Given:

23 B 4 D 45 A 9 C 11 = ?

New equation: 23 × 4 – 45 ÷ 9 + 11 = ?

23 × 4 – 5 + 11 = ?

92 – 5 + 11 = ?

103 – 5 = ?

? = 98

Thus, correct option is (d).

Correct Answer is: ETGPBGP

Given:

CLOCK → ANMEI

RADIO → PCBKM

Logic: Letters are shifted alternately −2, +2.

CLOCK → ANMEI

C −2 → A

L +2 → N

O −2 → M

C +2 → E

K −2 → I

RADIO: ?

R −2 → P

A +2 → C

D −2 → B

I +2 → K

O −2 → M

Now apply to GRINDER:

G −2 → E

R +2 → T

I −2 → G

N +2 → P

D −2 → B

E +2 → G

R −2 → P

So, GRINDER → ETGPBGP

Thus, correct option is (B).

Correct Answer is: OLDHUVB

Given: If FREEDOM is coded as IUGHGQP.

Correct Answer is: Only I follows

Statement:

The price of vegetables increased due to transport strike.

Conclusions:

I. Transport affects market prices.

This follows, because a transport strike leading to higher prices shows transport has an effect on prices.

II. Farmers caused the price rise.

This does not follow, because the statement clearly says the rise was due to a transport strike, not farmers.

So, Only I follows.

Thus, correct option is (a).

Correct Answer is: 15

Given:

In a line of 50 students, Rina is 20th from left and Tina is 15th from right.

Solution:

First convert Tina’s position to from left:

Position from left:

= 50 - 15 + 1

= 36

Now find the number of students between them:

= 36 - 20 - 1

= 15

So, 15 students are between them.

Thus, correct option is (b).

Correct Answer is: O

Given:

Six people, M, N, O, P, X and Y, are sitting in a row facing north.

Exactly four people sit between Y and O.

P sits second to the right of O.

N sits to the immediate right of X.

O sits to the immediate left of M.

Thus, the correct option is (c).

Correct Answer is: 1472

Series: 1412, 1420, 1430, 1442, 1456, ?

Logic: The differences are: 8, 10, 12, 14 → increasing by 2 each time

1420 − 1412 = 8

1430 − 1420 = 10

1442 − 1430 = 12

1456 − 1442 = 14

Next difference = 14 + 2 = 16

Next term = 1456 + 16 = 1472

Thus, correct option is (d).

Correct Answer is: Only II follows

Statement:

1. All teachers are educated.

2. Some educated people are researchers.

3. No researcher is careless.

From the given statements possible Venn diagram will be.

Conclusions:

I. Some teachers are researchers. (False, there is no relationt between teachers and researchers).

II. Some educated people are not careless. (True, some educated people are researchers and no researcher is careless, so that means Some educated people are not careless).

So, Only II follows.

Thus, correct option is (b)
