If the compound interest on a certain sum of money for 2 years at 10% per annum be Rs. 993, what would be the simple interest?  Answers:
A) Rs. 600
B) Rs. 890
C) Rs. 895
D) Rs. 900
E) None
Let P = Principal   Rs. 600 - Rs. 600mount   We have a = P(1 + R/100)3 and CI = Rs. 600 - P   Rs. 600TQ 993 = P(1 + R/100)3 - P   ? P = 3000/-   Now SI @ 10% on 3000/- for 2 yrs = (3000 x 10 x 2)/100   = 600/-   Rs. 600nswer: Rs. 600.
