Answer 1

Answer:

Let the marked price be x.

Let the cost price be 100.

Then the selling price = 100 + 8

                                     = 108.

Given that the dealer allows the discount of 10% on the marked price.

90% of x = 108

90/100 * x = 108

90 * x = 108 * 100

90 * x = 10800

x = 10800/90

x = 120.

Therefore the Marked price is 20% above the cost price.

Hope this helps
