Question 74

The following table shows the number of children in each house of a society.

What is the average number of children per house?

Solution

Total number of houses = 5 + 14 + 10 + 3 = 32

Total children = $$(0 \times 5) + (1 \times 14) + (2 \times 10) + (3 \times 3)$$

= 14 + 20 + 9 = 43

$$\therefore$$ Average number of children per house = $$\frac{43}{32} = 1.34$$

=> Ans - (A)
