Here is complete explanation of Which one of the following numbers can be removed from the….

Solution(By ExamCraze Team)

The average of the elements in the original set S is:
$$eqalign{ & frac{{0 + 2 + 4 + 5 + 9}}{5} cr & = frac{{20}}{5} cr & = 4 cr} $$ If we remove an element that equals the average, then the average of the new set will remain unchanged. The new set after removing 4 is {0, 2, 5, 9}. The average of the elements is, $$eqalign{ & frac{{0 + 2 + 5 + 9}}{4} cr & = frac{{16}}{4} cr & = 4 cr} $$
