If the simple interest on a sum of money for 3 years at 7% per annum is Rs. 570, what is the compound interest on the same sum at the rate and for the same time? Pick one:	A) Rs. 610.83	B) Rs. 810.83	C) Rs. 617	D) Rs. 618	E) Rs. 610.83
Sum = (570 * 100) / (7 * 3) = Rs. 2,714.29   Amount = [2,714.29 * (1 + 7/100)3] = Rs. 3,325.12   C.I. = (3,325.12 - 2,714.29) = Rs. 610.83.   ANSWRs. 610.83R:Rs. 610.83
