Atul has Rs.600 with him. He invested 30% of the amount
at 5% p.a. for 6 years and rest at 15% p.a. for 4 years. Find the sum of simple interests received by Atul from the two investments.Solution
SI received from 30% of the sum = (0.3 x 600 x 5 x 6)/100 = Rs.54 SI received from 70% of the sum = (0.7 x 600 x 15 x 4)/100 = Rs.252 Therefore, total SI received = Rs.(54 + 252) = Rs.306
