Question

sopkeeper allows a discount of 10% on the marked price. How much above the cost price
must be mark his goods to gain 8%?​

Answer 1

Answer:

let Marked price of an article be x

Discount on article =x−10%of x

=x−10/100

= x =0.9x

Therefore, selling price of the article=0.9x

Now, Gain % = SP−CP/CP

Put the value of gain % and sp in the above equation and calculate cp.

8/100=0.9x-cp/cp

8cp=90x-100cp

108cp=90x

cp=90x/108

cp=5x/6

Therefore, cost price cp marked above marked price(mp) = mp−cp/cp×100
