Question
Mr. X invested Rs. 700 in two schemes, A and B in the
ratio of 7:3, respectively. Scheme A and B are offering simple interest at rate of 5% per annum and 10% per annum. Find the total interest obtained from both schemes after 2 years.Solution
Amount invested in scheme A = (7/10) × 700 = Rs. 490 Amount invested in scheme B = (3/10) × 700 = Rs. 210 Interest earned from scheme A = 490 × 5% × 2 = Rs. 49 Interest earned from scheme B = 210 × 10% × 2 = Rs. 42 Therefore, required total interest = 49 + 42 = Rs. 91
