**Given:**

Contribution of A is (1/4) of the total capital for 15 months

Profit of B is (12/17) of the total profit

**Concept used:**

The ratio of profit of investors = Ratio of each investment in the given time duration

**Calculation:**

Let B invested capital for x year

Since, A's contribution is (1/4) of the total investment

So, the contribution of B = {1 - (1/4)}

⇒ (3/4) of the total contribution

And, B's profit = 12/17

So, A's profit = {1 - (12/17)}

⇒ 5/12

According to the concept, we have

(1/4) × (15/12) : (3/4) × x = (5/17) : (12/17)

⇒ (15/4)/(3x/4) = 5/12

⇒ (15 × 4)/(48 × 3x) = 5/12

⇒ (5/12x) = 5/12

⇒ x = 1

**∴ B invested his capital for 1 year.**
