NIMCET 2014 — Reasoning PYQ

Solution

Given:

Six family members: A, B, C, D, E, and F.

Professions: Psychologist, Manager, Advocate, Jeweller, Doctor, and Engineer.

 Analysis:

• Step 1: Determine the generations and couples.

  • A (Doctor) is the Grandfather of F and E. This confirms A is Male.

  • D is married to A. Therefore, D is the Grandmother (Female).

    $$\text{Couple 1: }A(+)⟷D(-)$$

• Step 2: Determine the second generation.

  • B is the mother of F and E.

  • C (Jeweller) is married to B (Advocate). Since B is the Mother (Female), C must be the Father (Male).

    $$\text{Couple 2: }C(+)⟷B(-)$$

• Step 3: Analyze the third generation (Children).

  • The children are F and E.

  • From the data: F is a Psychologist and E is an Engineer.

  • However, the information does not specify the gender of F or E. They could be grandsons, granddaughters, or one of each.

Final Gender Count:

• Males: A, C, and potentially F and/or E.

• Females: D, B, and potentially F and/or E.

Conclusion:

Since the genders of F and E are unknown, we cannot calculate the exact number of male members.

Hence, the answer can't be determined.
