The average weight of a family of five members (in kg) whose weights are 40 kg, 49 kg, 56 kg, 70 kg and 39 kg is:

• A. 49.8
• B. 52.8
• C. 51.8
• D. 50.8

Answer 1

Answer:

D. 50.8

Given weights:

40 kg, 49 kg, 56 kg, 70 kg, 39 kg

Find the total weight

$40 + 49 + 56 + 70 + 39$
$= 254 \text{ kg}$
Find the average

$\text{Average} = \frac{254}{5}$
$= 50.8$
