Applying for the same logic , 

For HDP : EAM,

Hence, the correct answer is "Option 4"

Question 692

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

In a certain code language,

A = B means ‘A is the son of B’,

A $ B means ‘A is the sister of B’,

A @ B means ‘A is the wife of B’ and

A * B means ‘A is the father of B’.

How is W related to G if ‘W = F $ K @ L * G’?

  1. AOption (a)

    Mother's sister's son

  2. BOption (b)

    Father's sister's son

  3. COption (c)

  4. DOption (d)

    Mother's brother's son

View answer & explanation

Correct answer

Answer: (a)A.

Mother's sister's son

Why this answer is correct

Given:

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

Symbol=$@*
MeaningSonSisterWifeFather

 

Given : ‘W = F $ K @ L * G’

 

From the diagram, K is the wife of L and L is the father of G, so K is the mother of G. F is the sister of K, making F the maternal aunt of G. Since W is the son of F, W is the Mother's sister's son of G.

Hence, the correct answer is 'Option 1'.

Question 693

    BCA−ZBA

  2. BOption (b)

    BDC−ACB

  3. COption (c)

    BDC−ZCA

  4. DOption (d)

    BCA−ACB

View answer & explanation

Correct answer

Answer: (b)B.

BDC−ACB

Why this answer is correct

The Logic followed here is:

For VXW is related to UWV,

For WYX is related to VXW,

Applying the same logic

For BDC is related to ACB,

 

Hence, the correct answer is "option 2"

Question 694

220 C 56 A 14 D 17 B 12 =?

  1. AOption (a)

    36

  2. BOption (b)

    30

  3. COption (c)

    20

  4. DOption (d)

    24

View answer & explanation

Correct answer

Answer: (c)C.

20

Why this answer is correct

The logic followed here is.

BODMAS Table: 

Letter Mappings:

ABCD
÷×+−

Replace the letters with their signs,follow the BODMAS order of operations:

= 220 + 56 ÷ 14 − 17 × 12

= 220 + 4 − 17 × 12

= 220 + 4 − 204

= 224 − 204

= 20

Hence, the correct answer is "option 3"
