Now in a set of 6 numbers if the lowest number is replaced by zero than the average of these numbers will be less than the original value.

Now in QTY B if we remove the lowest number then the average of these 5 nos. will always be greater than QTY A

in other words \(\frac{X}{6} < \frac{X}{5}\) (x = total number which will remain same in both cases)
