This question asks us to find the average weight of a family composed of five members. The average provides a central or typical value for a set of numbers. To calculate it, we sum all the individual values and then divide by the total number of values.
We can determine the average weight of the family by following these steps:
The given weights are: 40 kg, 49 kg, 56 kg, 74 kg, and 35 kg.
The sum of these weights is calculated as:
Total Weight = $40 + 49 + 56 + 74 + 35$ kg
Total Weight = $254$ kg
$ \text{Average Weight} = \frac{\text{Sum of Weights}}{\text{Number of Members}} $
Substituting the values we found:
Average Weight = $ \frac{254 \text{ kg}}{5} $
Average Weight = $ 50.8 $ kg
Thus, the average weight of this family of five members is 50.8 kg.
