The pie chart on the right shows the result of a survey carried out to find the modes of travel used by the children to go to school. Study the pie chart and answer the questions that follow.
(a) What is the most common mode of transport?
(b) What fraction of children travel by car?
(c) If 18 children travel by car, how many children took part in the survey?
(d) How many children use taxi to travel to school?
(e) By which two modes of transport are equal number of children travelling
(a) Since, bus has the highest central angle i.e., 120°
Hence, the most common mode of transport is the bus.
(b) 
(c) 
⇒ Total no. of Children = 18 × 4
⇒ Total no. of Children = 72
(d) Central angle of students who do not take taxi = 120° + 90° + 60° + 60°
⇒ Central angle of students who do not take taxi = 330°
⇒ Central angle of students who take taxi = 360° – 330°
⇒ Central angle of students who take taxi = 30°
⇒ No. of Children travelling by taxi = 6
(e) Since, the central angle for students travelling by cycle and those who walk is same.
Hence, the two modes of transport are equal number of children travelling are Cycle and Walk.
