1. 6
2. 9
3. 8
4. 7

Answer 1

Correct Answer - Option 3 : 8

Given: X invested Rs. 14400 for 3 years. Y invested Rs. 27000 for certain years.

Formula: Ratio of profits after investment = ratio of sum of the product of investment amount and the time invested for.

Calculation:

Let Y invested for x years.

X	Y
14400 × 3	27000 × x

ATQ,

14400 × 3/27000 × x = 1/5

⇒ 8/5x = 1/5

⇒ X = 8
