A person invested a certain amount in Scheme A at 15% per annum simple interest for two years and received ₹7,800 as total interest. The person increased the amount by ₹X and invested it in Scheme B at 10% per annum compound interest for two years and received ₹6,720 as interest. Find the value of X (in ₹).

1. 8000
2. 5000
3. 6000
4. 3000

Correct answer: 6000

Solution

From simple interest, SI = P × 15 × 2 / 100 = 7800, so P = 26,000. For two years at 10% compound interest, CI = 21% of principal, so 0.21(P + X) = 6720. Thus P + X = 32,000, giving X = 6,000.
