Answer 2

Let the Cost price be 100.

Then the selling price will = 112.

Let the marked price will be x.

Then, 80% of x = 112

= > x = (112 * 100)/80

         = 140.



Therefore Marked price = 140.

Now,

Cost price = 140 - 100

                  = 40.



Therefore the shopkeeper marks 40% above the cost price.
