# Tushar borrowed a sum of Rs. 12000 at 15% per annum from a money – lender on 13th January, 1987 and return the amount on 8th June, 1987 to clear his debt. Then the amount paid by Tushar to the money – lender to clear his debt was ?

A. Rs. 15000 B. Rs. 11394 C. Rs. 12720 D. Rs. 13650 Answer: Option C
Time = 18 + 28 + 31 + 30 + 31 + 8 = 146 days Simple Interest, $\begin{array}{l} =\frac{12000 \times 15 \times 146}{365 \times 100} \\ =\text { Rs. } 720 \\ \therefore \text { Amount will be } \\ =\text { Rs. }(12000+720) \\ =\text { Rs. } 12720 \end{array}$
