A sum of Rs.5800 is invested at a compound interest for three years, the rate of interest being 10% p.a., 20% p.a. and 25% p.a. for the 1st, 2nd and the 3rd years respectively. Find the interest received at the end of the three years.	Choose one
A) A)282	B) B)3770	C) C)8383	D) D)8383	E) E)3284
Let A be the amount received at the end of the three years.   A = 5800[1 + 10/100][1 + 20/100][1 + 25/100]   A = 5800 * 1.65   A = Rs.9570   So the interest = 9570 - 5800 = Rs.3770   Answer: 3770
