A shopkeeper marks his goods 40% above the cost price and allows a discount of 25% on it. His gain per cent is

Suppose C.P. of article = Rs. 100
∴ Its marked price = Rs. ( 100 + 40 ) = 140
Discount = 25%

∴ S.P. of article = Rs.		140 × 75		= Rs. 105
		100

Profit = S.P. of article - C.P. of article = 105 - 100 = Rs. 5

∴ Profit percent =	Profit	× 100
	C.P.

Profit percent =	5	× 100 = 5%
	100
