    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 = 175

    Correct 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
    Total number of students playing football all the school = 250 + 125 + 175 + 100 + 250 = 900
    Now, According to question,
    a % of 900 = 175

    ∴a × 900 = 175
    100

    ∴ a = 175 = 194%

    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
    Required difference = The total number of students playing Basketball from all the school - The total number of students playing Cricket from all the school

    Correct Option: B

    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
