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.   8110 = P + (54P/100)   8110 = (100P + 54P)/100   8110 = 154P/100   P = (8110 * 100)/154 = Rs. 5266.233   ANSWER Rs. 5266
