Question of the week – Solution

Click ‘more…’ to read the solution.

The correct answer is D.

Solution:
The average of the three numbers is 5, therefore the sum of the numbers is 15.

We know that one of the numbers is 7, so we can calculate to see what the sum of the remaining two numbers is:
15 – 7 = 8

If the sum of the remaining two numbers is 8, and all numbers are positive, none of the remaining numbers can be 9.
