Question
Vishal has certain sum of money with him. He invested
80% of the sum in scheme βXβ offering 15% p.a. simple interest for 8 years and received Rs. 2640 as interest. He then invested the amount received from scheme βXβ in scheme βYβ for 2 years at 50% p.a., compound interest compounded annually. Find the amount received by Vishal from scheme B.Β ΒSolution
Let, Vishal invested Rs. x in scheme βXβ According to the question, {(x Γ 15 Γ 8)/100} = 2640 Or, x = 2640/1.2 Or, x = 2200 Total sum Vishal had = 2200/0.8 = Rs. 2750 Amount received from scheme βXβ = 2200 + 2640 = Rs. 4840 Amount received from scheme βYβ = 4840(1 + 50/100)2 = Rs. 10890
