Question
A certain sum when invested for 3 years in a scheme offering simple interest of 12% p.a. gives an interest of Rs. 802.8. What is 170% of the sum invested?
Solution
Let the sum invested = Rs. 100Y Then interest earned = 100Y × (0.12 × 3) = Rs. 36Y Or, 36Y = 802.8 Or, Y = (802.8/36) = 22.3 So, sum invested = Rs. 2230 170% of sum invested = 2230 × 1.70 = Rs. 3791
