The profit of store A increases from \(20%\) to \(24%\)while the profit of store B decreases from \(24%\) to \(20%\).

Quantity A

Percentage increase in store A's profit

Quantity B

Percentage decrease in store B's profit

In this problem, we know that the percent increase would 4/20 for A.

For B, the percent decrease would be 4/24.

If the denominator are bigger while the numerator are the same, the one with bigger denominator would be smaller.

so, A>B
