The average weight of a family of five members (in kg) whose weights are 40 kg, 49 kg, 56 kg, 69 kg and 37 kg is:

Correct option is D

Given:

Weights of the five family members: 40 kg, 49 kg, 56 kg, 69 kg, and 37 kg.

Formula Used:

Average =$$\frac {\text{ (Sum of all values) }}{\text{(Number of values)}}$$​​

Solution:

Sum = 40 + 49 + 56 + 69 + 37 = 251 kg.

Average ​ = $$\frac{251 kg } 5$$​= 50.2 kg.

Therefore, the average weight of the family is 50.2 kg.
