Question 986078
Lets find the total number of students. First understand what 28% really say. It says if theres hundred students in school, 28 come by car.

Total number of students = 231x 100/28 = 825

517 walks. So the remaining goes by PMV, number of students go by PMV = 308

So the percentage = 517/825 x 100 = 62.67%

Dont forget to thank.
