A) Gain 10%
B) Loss 10%
C) Loss 9%
D) No profit no loss
Correct Answer: B
Solution :
Let the cost price = Rs. 100 |
\[\therefore \] Marked price = Rs. 150 |
Rate of discount on marked price = 40% |
Selling price = Rs. \[(150-\frac{40}{100}\times 150)\] |
= Rs.\[=\left( \frac{1}{8}\text{of}\frac{8}{5} \right)=\frac{1}{5}\]= Rs. 90 |
\[\therefore \] Loss \[=100-90\]= Rs. 10 |
\[\therefore \] Loss per cent\[=\frac{10}{100}\times 100=10%\] |
