| A wholesale rice merchant sells a bag containing 50 kg of rice for Rs. 1500. He allows two discount of 10% and 5%. How much money a customer has to pay to the bag of rice? |
A) Rs. 1282.50
B) Rs. 1245.50
C) Rs. 1260.25
D) Rs. 1236.25
Correct Answer: A
Solution :
| Marked price of a bag of rice = Rs. 1500 |
| Discount of 10% on \[\text{Rs}\text{. 1500}=\frac{(100-10)}{100}\times 1500\] |
| \[=\frac{90}{100}\times 1500=90\times 15\] |
| \[=1350\] |
| Again, discount of 5% on \[\text{Rs}\text{. 1350}=\frac{(100-5)}{100}\times 1350\] |
| \[=\frac{95}{100}\times 1350=\frac{95\times 135}{10}\] |
| \[=\frac{12825}{10}=1282.50\] |
