Maya had Rs. 12000 with her. She invested 30% of the sum
at 8% p.a. and the rest at 18% p.a., both at simple interest for 5 years each. Find the total interest received by Maya.Solution
ATQ, Interest received by Maya at 30% of the sum = (0.30×12000×8×5)/100=Rs.1440 Interest received by Maya on 70% of the sum = (0.70×12000×18×5)/100=Rs.7560 Therefore, total interest received = 1440 + 7560 = Rs. 9000
