Question

A shopkeeper marks his goods at 40% above the cost price and offers a discount of 20%. What is his gain
per cent?​

Answer 1

Step-by-step explanation:

Let cost price be Rs. x

Marked price = x + 40% of x = 140x/100 = Rs. 7x/5

Discounted price (or selling price)

= 7x/5 - 25% of 7x/5

= 7x/5 - 7x/20

= Rs. 21x/20

Gain = SP - CP = 21x/20 - x = Rs. x/20

Gain % = (Gain/CP) *100

= (x/20x)*100

= 5%
