Question

if a merchant want to give 10% discount on the cost price, he has to sell it for Rs. 495 if he sell it for Rs. 660, find the gain or loss%?​

Answer 1

Answer:

20% gain

Step-by-step explanation:

given that by giving 10% discount ,the price is Rs. 495,

let original price before discount be x,

therefore,

0.9x = 495,

=> x = 495/0.9,

=> x = 550,which is cost price.

given he sold it for Rs. 660/-,

so gain % = [(660-550)/550]*100,

=> gain % = (110/550)*100,

=> gain % = 20%.
