As per given table, we can see that,
Number of students playing football from all the given school
A = 250 , B = 125 , C = 175 , D = 100 , E = 250
Total number of students playing football all the school = 250 + 125 + 175 + 100 + 250 = 900
Now, According to question,
a % of 900 = 175Correct Option: B
As per given table, we can see that,
Number of students playing football from all the given school
A = 250 , B = 125 , C = 175 , D = 100 , E = 250
