RRB ALP 2025 CBT 2 Heat Engine Question Paper (28-Jul-2026) (Shift 2)
The correct answer is
Mother's father's sister

Let's decode the relationships step by step based on the given coding rules:

  • Rule 1: 'A + B' means 'A is the mother of B'.
  • Rule 2: 'A - B' means 'A is the brother of B'.
  • Rule 3: 'A × B' means 'A is the sister of B'.
  • Rule 4: 'A ÷ B' means 'A is the father of B'.

Expression Analysis: P × S ÷ R - Q + T

We analyze the expression using the provided codes:

  1. P × S: From Rule 3, P is the sister of S.

  2. S ÷ R: From Rule 4, S is the father of R.

    Combined: P is the sister of R's father. Thus, P is R's paternal aunt.

  3. R - Q: From Rule 2, R is the brother of Q.

    Combined: Since P is R's paternal aunt, P is also Q's paternal aunt. This means P is the sister of Q's father.

  4. Q + T: From Rule 1, Q is the mother of T.

    Combined: P is the sister of Q's father. Q is T's mother. Therefore, P is the sister of T's mother's father (T's maternal grandfather).

Relation of P to T

P is the sister of T's maternal grandfather. This relationship is known as a maternal grand-aunt.

Specifically, this corresponds to T's mother's father's sister.
