From above diagram ,
The total number of students who come to school by car is represented in pie chart = 70°
The total number of students who come to school by bus is represented in pie chart = 90°
Required ratio = 70° : 90° = 7 : 9 = 21 : 27
Expenditure increased = Expenditure in 1997 ? 98 - Expenditure in 1993 ? 94
Expenditure increased = 8800 ? 5100 = 3700.
As per given table, we can see that,
Number of students playing Basketball from all the given school
A = 200 , B = 195 , C = 245 , D = 200 , E = 225
Number of students playing Cricket from all the given school
A = 150 , B = 200 , C = 250 , D = 230 , E = 200
The total number of students playing Basketball from all the school = 200 + 195 + 245 + 200 + 225 = 1065
The total number of students playing Cricket from all the school = 150 + 200 + 250 + 230 + 200 = 1030
Required difference = The total number of students playing Basketball from all the school - The total number of students playing Cricket from all the school
Required difference = 1065 ? 1030 = 35
