The marked price of an electric iron is ₹ 300. The shopkeeper

The marked price of an electric iron is ₹ 300. The shopkeeper allows a discount of 12% and still gains 10%. If no discount is allowed, his gain per cent would have been :

Here , The marked price of an electric iron = ₹ 300
Discount = 12%
According to question ,
SP of electric iron = 88% of 300

SP of electric iron = ₹	300 × 88	= ₹ 264
	100

Profit = 10%

∴ CP of electric iron =	100	× 264 = ₹ 240
	110

After no discount,
Gain = 300 – 240 = ₹ 60

Gain percent =	60	× 100 = 25%
	240

Second Method :
Here, M.P. = ₹ 300, r = 10%, D = 12%.
With the help of given formula ,

M.P.	=	100 + r
C.P.	=	100 − D

300	=	100 + 10
C.P.	=	100 − 12

C.P. =	300 × 88
	110

Gain % (without discount) =	300 − 240	× 100 = 25%
