ATQ,
Interest to be paid by Amit at 10% p.a. after 3 years = (36000 × 10 × 3) / 100 = Rs. 10800 Interest earned by Amit at 13% p.a. after 3 years = (36000 × 13 × 3) / 100 = Rs. 14040 Therefore, amount gained by him in 3 years = 14040 – 10800 = Rs. 3240 Therefore, annual profit of Amit = 3240 / 3 = Rs. 1080
