offering simple interest of 16% p.a. gives an interest of Rs. 1128. What is 160% of the sum invested?Solution
Let the sum invested = Rs. 100Y Then interest earned = 100Y × (0.16 × 3) = Rs. 48Y Or, 48Y = 1128 Or, Y = (1128/48) = 23.5 So, sum invested = Rs. 2350 160% of sum invested = 2350 × 1.60 = Rs. 3760
