The marked price of a radio set is Rs. 480. The shopkeeper allows discount of 10% and gains 8%. If no discount is allowed, his gain percent would be
Marked price = 480
Sold price after giving discount will be = $$\frac{480\times90}{100}$$ = 432
Gain = 8%
 As when cost price is 100 and gain is 8% sold price is 108 so when sold price is 432 then cost price will be $$\frac{432}{1.08} = 400$$
Now without discount sold price will be 480 , hence gain is 80 rs.
%gain = $$\frac{80\times100}{400}$$
