Question 85(iii)
The pie chart given below shows the result of a survey carried out to find the modes of travel used by the children to go school. Study the pie chart and answer the questions that follow.
If 18 children travel by car, how many children took part in the survey ?
We know that, fraction of children travel by car =14
Hence, total number of children travelled by car =14× Total number of children
⇒18=14× Total number of children
∴ Total number of children =18×4=72
