By selling 80 oranges, a man gains the cost price of 20 oranges. Find the gain percentage.
Hello Simran .
The answer of your question is 25%.
To explain let cost of one apple is X 80 apple cost =80x.
20 apple cost =20x.
Profit%= (sp-cp)cp *100
.
Sp=80x+20x.
Cp=80x
Profit%=(80+20-80)X/80x*100 ===. 25%.
Hope you get it.
Good luck
