• D. D, G, C, E

Hint:

Use elimination and group language intersections systematically in such logical grouping questions.

Answer 1

The Correct Option is C

Step 1: Identify the language groups
From the passage:
- A: Gujarati, speaks Tamil and Bengali
- B: Bengali only
- C: Gujarati, speaks Tamil
- D: Tamilian only
- E: Gujarati, speaks Bengali
- F: Bengali only
- G: Tamilian only Step 2: Apply constraints
- Bengalis and Tamilians cannot share a room.
- Each person in a room must share a language with at least one other person.
Step 3: Check Option (C) — Room 1: A, D, E, G
- A: shares Tamil with D and G, Bengali with E
- D and G: both Tamilian
- E: shares Bengali with A
Room 2: B, C, F
- B and F: Bengali
- C: speaks Tamil, but cannot share with Bengali — invalid
So C must be in the Tamil group. Option (C) is the only valid arrangement where both room sets avoid conflicts and maintain mutual language understanding.
