Question
Vishal has certain sum of money with him. He invested
80% of the sum in scheme ‘X’ offering 15% p.a. simple interest for 8 years and received Rs. 3960 as interest. He then invested the amount received from scheme ‘X’ in scheme ‘Y’ for 2 years at 50% p.a., compound interest compounded annually. Find the amount received by Vishal from scheme B. ÂSolution
Let, Vishal invested Rs. x in scheme ‘X’ According to the question, {(x × 15 × 8)/100} = 3960 Or, x = 3960/1.2 Or, x = 3300 Total sum Vishal had = 3300/0.8 = Rs. 4125 Amount received from scheme ‘X’ = 3300 + 3960 = Rs. 7260 Amount received from scheme ‘Y’ = 7260(1 + 50/100)2 = Rs. 16335Â
