Question

how much percent above the cost price should a shopkeeper mark his good so after allowing a discount of 10%on the marked price he earns a profit of 8%​

Answer 1

Answer:

18.8%

Step-by-step explanation:

say the marked prices 88.

10% discount means 80

8% gain means

80=108% of cp

or cp would be 80/1.08

=40/0.54=20/0.27=74.07

Now we calculate how many % is 88 above 74.07

So 88/74.07=1.188

This is 18.8%marking above actual cp .
