Question

The average weight of a family of five members (in kg) whose weights are 40 kg, 49 kg, 56 kg, 66 kg and 35 kg is:

• A. 51.2
• B. 50.2
• C. 49.2
• D. 48.2

Answer 1

Answer:

C. 49.2

To find the average weight, use the formula:

$\text{Average} = \frac{\text{Sum of all weights}}{\text{Number of members}}$

Step 1: Find the total weight

$40 + 49 + 56 + 66 + 35 = 246 \text{ kg}$

Step 2: Divide by number of members (5)

$\frac{246}{5} = 49.2$

The average weight of the family is 49.2 kg.
