Question

5. A dealer allows a discount of 12% on the marked price. How much per cent above the cost price,
must he mark his goods so as to make a profit of 10%?​

Answer 1

Answer:

Step-by-step explanation:

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!
