Question

when the price of an artical was decreased by Rs4, 3 more articles could be bought for Rs.360.find the original price of the article.​

Answer 1

Answer:

let original price be x

quantity purchased = 360/x

new price = x-4

new quantity = 360/ x-4

difference in both quantities = 3

ie (360/ x-4) - (360/x) =3

3x² -12x - 1440 =0

or x² - 4x - 480 = 0

solving it we get x = -20 or x =24

so answer is 24 rupees
