Question

In a certain code language,

'A : B' means 'A is the wife of B',

'A ! B' means 'A is the brother of B',

'A < B' means 'A is the son of B' and

'A / B' means 'A is the father of B'.

How is S related to E if 'S < H: A ! M / E'?

• A. Father's brother's brother
• B. Father's brother's mother
• C. Father's brother's daughter
• D. Father's brother's son

Answer 1

Answer:

D. Father's brother's son

Decode the expression step by step:

Given meanings:

• A : B → A is wife of B

• A ! B → A is brother of B

• A < B → A is son of B

• A / B → A is father of B

Expression:
S < H : A ! M / E

Break it

1) S < H

S is son of H

So H is parent of S.

---

2) H : A

H is wife of A
So A is husband of H.

---

3) A ! M

A is brother of M
So A and M are siblings.

---

4) M / E

M is father of E

So:

• M → E (father-child)

• A is M’s brother → A is also in same generation as M

  Build relationships

• M is father of E

• A is brother of M → A is uncle of E

• H is wife of A → H is aunt-in-law of E

• S is son of H (and A)

So S is child of A and H.

Relation between S and E

• A is uncle of E

• S is A’s son

So S and E are in same generation but different branches.

Therefore, S is cousin of E

Final Answer: Father's brother's son
