Use some thinking to answer the following question. What amount does Kiran get if he invests Rs. 18000 at 15% p.a. simple interest for four years?
Options:
(A) 22777
(B) 28877
(C) 26888
(D) 28800
(E) 67881
Simple interest = (18000 * 4 * 15)/100 = Rs. 10800
Amount = P + I = 18000 + 10800 = Rs. 28800 So the final answer is (D).
