Question
Atul has Rs.400 with him. He invested 40% of the amount
at 4% p.a. for 5 years and rest at 15% p.a. for 3 years. Find the sum of simple interests received by Atul from the two investments.Solution
SI received from 40% of the sum = (0.4 x 400 x 4 x 5)/100 = Rs.32 SI received from 60% of the sum = (0.6 x 400 x 15 x 3)/100 = Rs.108 Therefore, total SI received = Rs.(32 + 108) = Rs.140
