A person invested certain amounts in three different schemes A, B, and C at simple interest rates of 8% p.a., 10% p.a., and 13% p.a. respectively. If the total interest in one year was ₹3,360 and the amount invested in Scheme C was 300% of the amount in Scheme A and 400% of the amount in Scheme B, what was the amount invested in Scheme A?

Question

Accepted Answer

1. Let amount in A be $x$. Then C = $3x$ and B = $\frac{3x}{4}$. 
2. Yearly interest: $0.08x + 0.10	imes\frac{3x}{4} + 0.13	imes3x = 3360$. 
3. Sum gives $0.545x = 3360$. 
4. So $x = 3360/0.545 \approx 6165$. 
5. Amount in A is ₹6,165, so the correct choice is **(c)**.
