    BFI

  4. DOption (d)

    PTW

View answer & explanation

Correct answer

Answer: (a)A.

QNJ

Why this answer is correct

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

Logic: First letter + 4 = Second letter; Second letter + 3 = Third letter.

For QNJ,

For GKN,

For  BFI,

For PTW,

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

Hence, the correct answer is 'Option 1'.

Question 356

RRB NTPC 2026• General Intelligence and Reasoning• General Intelligence and Reasoning

In a certain code language,

A @ B means ‘A is the mother of B’,

A × B means ‘A is the wife of B’,

A + B means ‘A is the brother of B’ and

A ÷ B means ‘A is the father of B’.

How is S related to H if ‘S × D + R ÷ Y @ H’?

  1. AOption (a)

    Father's brother's wife

  2. BOption (b)

    Mother's father's brother's daughter

View answer & explanation

Correct answer

Answer: (d)D.

Mother's father's brother's wife

Why this answer is correct

Family Chart:

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

Symbol@×+div
MeaningMotherWifeBrotherFather

 

Given: ‘S × D + R ÷ Y @ H’

 

From the family tree, it is evident that Y is the mother of H, and R is the father of Y (making R the maternal grandfather). D is the brother of R, and S is the wife of D. Therefore, S is the Mother's father's brother's wife of H.

Hence, the correct answer is 'Option 4'.
