Solution

Help most in house work Number of children

Going to the market 47

Washing utensils 15

Washing clothes 3

Making, serving food 25

Cleaning the house 10

Total children who said
they help their parents
100

Total number of children who said they help their parents = 47 + 15 + 3 + 25 + 10
= 100
The chapati chart is shown below:

Correct: (c)
Number of children who help in making and serving food = 25
Now, fraction of total children who help in making and serving food = $\frac{25}{100}$
= $\frac{1}{4}$
Thus, one-fourth of the total children help in making and serving food.
