If a shopkeeper marks the price of goods 50%, more than their cost price and allows a discount of 40%, what is his gain or loss per cent?

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\[=\frac{10}{100}\times 100=10%\]
