Question

J sells an article to K at the loss of 30%. K sells the same article to L at the profit of 40%. If L pays rs. 490 at last then find the starting selling price of article​

Answer 1

Step-by-step explanation:

let x be the price of the article

therefore,

J selling price = x-30%of x = x -30x/100=x-0.3x= 0.7x

K selling price= x + 40%of x = x+0.4x= x+0.4x= 1.4x

we know the selling price of K = 490

1.4 x = 490

x = 490/1.4= 350

therefore J selling price = 0.7x= 0.7×350= 245
