B

Profit = y-x

1) y-x = 20
Percent = P/x *100 = 20/x *100
Not suff

2)y/x = 5/4

Hence P = 5x/4 - x = x/4

Percent = x/4/x * 100 = 100/4 = 25

The author gives us the following info:

cost=x
revenue=y
gross profit=y-x

statement 1) y-x=20 or a gross profit of 20.... but we cannot determine how many dollars was the cost of an item so cannot determine the percentage....

statement 2) gives us the value of y (the revenue) and x (the cost) so we can determine the gross profit and the percentage of gross profit of the cost of the item..... answer 1/4=25%
