Question

A dress marked at 120 rs and discount 20% find the sale price

Answer 1

Step-by-step explanation:

marked price = 120rs

discount = 20%

let the selling price be 100

then ,

$selling \: price \: = \frac{(100 + profit)cost \: price}{100} \\ \\ = \frac{(100 + 20)120}{100} \\ \\ = \frac{120 \times 120}{100} \\ \\ = \frac{14400}{100} \\ \\ = 144 \\ \\ selling \: price \: \: is \: 144$
