A) s. 5266	B) s. 5269	C) s. 5228	D) s. 5201	E) s. 52192
Explanation:   Let us assume Mr. Karan borrowed amount is Rs. A. (the principal)   By formula of simple interest, S.I. = PRT / 100   Where P = The principal, R = Rate of interest as a %, T = Time in years   S.I. = (P * 6 * 9)/100 = 54 P/100   Amount = Principal + S.I.   8010 = P + (54P/100)   8010 = (100P + 54P)/100   8010 = 154P/100   P = (8010 * 100)/154 = Rs. 5201.298   ANSWER: s. 5201
