Question

The ratio of cost price and marked price is 9:11 ,If the profit percentage and discounts percentage are the same, then profit percentage?​

Answer 1

Step-by-step explanation:

we have given that ratio of CP :MP=9:11 then assume that CP =9x and MP =11x if profit%=discount%

we know that profit%=profit*100/CP

discont%=discount/MP*100. and discount=MP-CP

discount=11x-9x=2x

profit%=discount% or

profit*100/CP = discount/MP *100

profit*100/9x=2x/11x *100

profit=200x *9x /11x *100

profit=18x/11

profit%=profit *100 /CP

profit%=18x/11 *100 /9x =200/11 =18.1%

profit%=18.1%
