Question

How much percent above the cost price should a shopkeepermark h8s good so that after all9wing a discount of 10%on the marked price,he earns a profit of 8%​

Answer 1

Answer:

20%

Step-by-step explanation:

say marked price is 100

10% down means 90

gain is 8%

So cp is 90/1.08

=83.33

Now We have to calc

100/83.33 as percentage

So 100-83.33=16.66

and 16.66 is (16.66/83.33) of 83.33

or (16.66/83.33)*100

=mark~20% above cost price
