Question
Mr. X invested Rs. 900 in two schemes, A and B in the
ratio of 7:3, respectively. Scheme A and B are offering simple interest at rate of 7% per annum and 12% per annum. Find the total interest obtained from both schemes after 2 years.Solution
Amount invested in scheme A = (7/10) × 900 = Rs. 630 Amount invested in scheme B = (3/10) × 900 = Rs. 270 Interest earned from scheme A = 630 × 7% × 2 = Rs. 88.2 Interest earned from scheme B = 270 × 12% × 2 = Rs. 64.8 Therefore, required total interest = 88.2 + 64.8 = Rs. 153
