| List price of a book is Rs. 100. A dealer sells three such books for Rs. 274.50 after allowing discount at certain rate. Find the rate of discount. |
A) 8.33%
B) 8.16%
C) 8.5%
D) 8.34%
Correct Answer: C
Solution :
| Here, list price of a book = Rs. 100 |
| Then, list price of 3 such books = Rs. 300 |
| Selling price of three books = Rs. 274. 50 |
| Discount \[=300-274.50=Rs.\,25.50\] |
| Discount percent \[=\frac{25.50}{300}\times 100=8.5\]% |
