A man deposited Rs. ‘x + 1300’ at 12% per annum simple interest and earned Rs. 852 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 + 1300) × 0.12 × 2 = 852 0.24x + 312 = 852 x = 540/0.24 = 2250 So, required interest earned = 2 × 2250 × 0.21 = Rs. 945
