A certain candy manufacturer reduced the weight of Candy Bar M by 20% but left the price unchanged. What was the resulting percent increase in the price per ounce of Candy Bar M ?

a.5%
b.10%
c.15%
d.20%
e.25%

The ans is E.
I am not able to determine what is the percent increase in the price when the price was unchanged. Any help would be great.
Thanks.

So let the weight of the candy be x units and the price be y
So its price per unit weight is y/x

New weight of the candy is 0.8 x but price remains unchanged i.e. y
So new price per unit is y/0.8x which is 5y/4x

So obviously you see 5y/4x is greater than y/x because 5/4 > 1
So the percentage of price per unit weight has increased.
The percentage increase is (5y/4x - y/x)*100/(y/x) = (5/4 - 1)*100 = 100/4 = 25%
200 or 800. It don't matter no more.
