A man deposited Rs. ‘x + 1000’ at 12% per annum simple interest and earned Rs. 528 as interest after 2 years. Find the interest earned by him if he deposited Rs. 2x at 10% per annum for 2 years at compound interest.
So, {(x + 1000) × 0.12 × 2 = 528 0.24x + 240 = 528 x = 288/0.24 = 1200 So, required interest earned = 2 × 1200 × 0.21 = Rs. 504
