| A dealer offered a machine at a discount of 5% but marked 20% highest than the cost price, then the profit per cent is |
A) 14%
B) 15%
C) 20%
D) 21%
Correct Answer: A
Solution :
| Let CP of machine = Rs. 100 |
| Then, MP \[=100+20=120\] |
| \[\text{SP}=\frac{100-\text{Discount}}{100}\times \text{MP}\] |
| \[=\frac{100-5}{100}\times 120=\frac{95}{100}\times 120=114\] |
| \[\text{Profit}=114-100=14\] |
| \[\therefore \] \[\text{Profit }%=\frac{14}{100}\times 100=14%\] |
