Q. What is the profit percentage?

I. The cost price is 80% of the selling price.
II. The profit is Rs 50.

Read Solution (Total 1)

Given CP is equal to 80% of SP
Therefore CP=(80/100*SP)=(4/5)SP
Given profit=50 we know SP-CP=Profit
50=SP-4/5SP,on solving SP=250 and CP=200 profit percentage=(profit/CP*100)
therefore p%=(50/200*100)=25%
