Here

let's take the numbers from 1 to 5

So the average of the numbers = $$\frac{15}{5} =3$$

Now if we remove a number what will be the average? to get that we need to take the greatest number from the series

So in this case , 5 is the greatest

So average of 1 ,2 ,3 ,4 =$$\frac{10}{4}= 2.5$$

Therefore the percentage decrease = $$\frac{{3 - 2.5}}{3} * 100 = 16.66%$$, this the maximum value we can get if we remove from the set.

Hence QTY A < QTY B

*** it can be any 5 consecutive positive numbers the maximum value will be 16.66%****
