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 schoolCorrect 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

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

∵ percentage = The number of men working in the Marketing department x 100 % the total number of employees in the organisation
Correct Option: A
As per given data ,
The total number of employees in the organisation = 520
Ratio of men to women in the organisation = 5 : 3
Number of men in the organisation = 5 x 65 = 325
% of the number of men working in the Marketing department = [ 100 - ( 40 + 20 + 4 ) ]% = 36%
The number of men working in the Marketing department = 325 of 36% = 117∵ percentage = The number of men working in the Marketing department x 100 % the total number of employees in the organisation = 117 x 100 = 22.5 % 520
