DIRECTIONS for the question:Solve the following question and mark the best possible option.
The average of 30 numbers is zero. Of them, at the most, how many can be greater than zero?
A)
0
B)
1
C)
15
D)
29
E)
None of these
D
Average of 30 numbers = 0. Sum of 30 numbers = (0 * 30) = 0. It is quite possible that 29 of these numbers may be positive and one negative number could be of very high value. So then their sum can be zero.
