Problem Solving (PS) | Re: If the gross profit of a certain company is 20 percent of the revenue

Let Profit P, revenue R and Cost C
So as Profit= Revenue -Cost
P=R-C

Given P= 20% of R = 20/100 * R =R/5 => R=5P

Putting in above equation => P =5P-C => C=4P => P=C/4
=> P= 25/100 * C
=> P = 25% of C

Answer: B
