NIMCET 2014 — Reasoning PYQ

Given:

A family of six members (A, B, C, D, E, and F) with different professions.

• Step 1: Identify the relationship between A and the grandchildren.

  The problem states that the Doctor is the grandfather of F.

  From the clues, D (Manager) is married to A. Since A is the spouse of the Grandmother/Grandfather and we are looking for the "Grandfather" figure, A is identified as the Doctor.

• Step 2: Map the family tree.

  • A (Doctor) is the Grandfather.

  • D (Manager) is the Grandmother.

  • B and C are the parents (Middle generation).

  • F and E are the children (Third generation).

Mathematical/Logical Representation:

• Let $(+)$ denote Male and $(-)$ denote Female.

• The generational gap is represented by the downward arrow.

Conclusion:

Since A is the father of the parent generation and the grandfather of F, he is also the Grandfather of E.
