Question

The average weight of a family of five members (in kg) whose weights are 40 kg, 49 kg, 56 kg, 70 kg and 35 kg is:

• A. 50
• B. 52
• C. 51
• D. 49

Answer 1

Answer:

A. 50

To find the average weight:

Add all weights

40 + 49 + 56 + 70 + 35 = 250

Divide by number of members (5)

$\text{Average} = \frac{250}{5} = 50$

= 50 kg
