QUESTION: 268

The average (arithmetic mean) of eight numbers is 44.1. If the sum of half of these numbers is 158.4, what is the average of the other half?

12.8
24.2
48.6
72.1
96.8

Answer(s): C

Explanation:

This is an average problem, so use the average formula. If the average of 8 numbers is 44.1, we can solve for their sum: 8 × 44.1 = 352.8. If four of these numbers total 158.4, then by subtracting 158.4 from 352.8, we get the sum of the other four numbers, 194.4. To find the average of these 4 numbers, we divide their sum by their number: 194.4/4 = 48.6.
