A trader allows a discount of 15% of the marked price if his article. How much above the cost price should he mark to gain 19% ?

Explanation

Given

Let the CP` = Rs.100`

Then SP`= 100 + 19 = Rs.119`

Let the marked price be` Rs. x`

Then `85% of x = 119`

`85/100xx(x) = 119`

`x = 119xx100/85 =140`

Marked price `= 40%` above CP
