Question

By selling 75 apples the seller gains the cost price of 15 apples. find his gain percentage. Please do with all step by step process. It will be easy for me to understand​

Answer 1

Answer:

20% profit

Step-by-step explanation:

suppose the cp is re 1

so the profit on 75 apples = sp of 75 apples - cp of 75 apples

as per the question profit = cp of 15 apples

cp of 15 = sp of 75 - cp of 75

cp of 90 apples = sp of 75

so cp/sp = 75/90

profit as per this ratio is 15 so the profit % = 15*100/75 = 20
