Correct Answer - Option 3 : 8

**Given:**

Ravi and Rashmi invested Rs. 150 and Rs. 200

Profit sharing ratio = 1 : 2

**Concept used:**

Profit sharing ratio = base of investment × time

**Calculation:**

Rashmi has invested for 12 months

So, Rashmi's total investment = 200 × 12

⇒ 2400

⇒ 2 → 2400

⇒ 1 → 1200

So, Ravi's total investment = 1200

He invested for 1200/150 = 8 months

**∴ After 8 months Ravi took out his money.**
