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 ?

 50%
 40%
 60%
 45%
Correct Option: A
Let the C.P. be ₹ 100 and the marked price be ₹ p.
∴ p ×  = 132  
100 
⇒ p =  
88 
= 150 i.e., more by 50%
∴ Required percentage = 50%
2nd method to solve this question.
Here, Gain % = 32%,, r_{1} = 12%, r = ?
Gain % =  − r_{1}  
100 
32 =  − 12  
100 
44 =  
100 
r = 50%
