Question
Atul has Rs.450 with him. He invested 20% of the amount
at 5% p.a. for 8 years and rest at 25% p.a. for 3 years. Find the sum of simple interests received by Atul from the two investments.Solution
SI received from 20% of the sum = (0.2 x 450 x 5 x 8)/100 = Rs.36 SI received from 80% of the sum = (0.8 x 450 x 25 x 3)/100 = Rs.270 Therefore, total SI received = Rs.(36 + 270) = Rs.306
