How much percent above the cost price should a shopkeeper

How much percent above the cost price should a shopkeeper mark his goods so as to earn a profit of 32% after allowing a discount of 12% on the marked price ?

Given in question , Profit = 32% and discount = 12%
Let the C.P. be 100 and the marked price be y.

∴ y ×	88	= 132
	100

⇒ x =	132 × 100
	88

= 150 i.e., more by 50%
Second method to solve this question :
Here, r = 12% , R = 32%

Required percentage =		r + R	× 100		%
		100 − r

Required percentage =		12 + 32		× 100%
		100 − 12

Required percentage =	44	× 100 = 50%
	88
