The average of a set of six positive numbers is 30.
Quantity A |
Quantity B |
The average of the numbers in the set after replacing the smallest number in the set with 0 |
The average of the remaining numbers in the set after removing the smallest number from the set |
A) Quantity A is greater.
B) Quantity B is greater.
C) The two quantities are equal.
D) The relationship cannot be determined from the information given.
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)
