A certain sum when invested for 3 years in a scheme
offering simple interest of 10% p.a. gives an interest of Rs. 756. What is 130% of the sum invested?Solution
Let the sum invested = Rs. 100Y Then interest earned = 100Y × (0.10 × 3) = Rs. 30Y Or, 30Y = 765 Or, Y = (765/30) = 25.5 So, sum invested = Rs. 2550 130% of sum invested = 2550 × 1.3 = Rs. 3315
