A trader marks his goods 40% above cost price and allows

A trader marks his goods 40% above cost price and allows a discount of 25 %. The profit he makes, is :

Let the cost price be ₹ 100.
Marked price = ₹ 140

S.P.=	75 × 140	= ₹ 105
	100

∴ Profit percent = 5%
2nd method to solve this question.
Here, r = 40%, r₁ = 25%

Profit % =	r ×(100 − r₁)	− r₁
	100

=	40 × (100 − 25)	− 25
	100

=	40 × 75	− 25
	100

=	3000	− 25
	100

Profit % = 30 – 25 = 5%
