Options- A. A and D
- B. B and D
- C. C and F
- D. E and F
- Correct Answer
- A and D
ExplanationAs per first graph,
The number of students for course A = Total number of students x 20%
As per second graph,
The number of girls for course A = Total number of girls x 30%
Number of boys in course 'A' = The number of students for course A - The number of girls for course A
Number of boys in course 'A' = (1200 x 20/100 ) - ( 800 x 30/100 ) = 240 - 240 = 0
Similarly,
Number of boys in course 'B' = (1200 x 15/100 ) - (800 x 10/100) = 180 - 80 = 100
Number of boys in course 'C' = (1200 x 5/100 ) - (800 x 2/100) = 60 - 16 = 44
Number of boys in course 'D' = (1200 x 35/100 ) - (800 x 30/100) = 420 - 240 = 180
Number of boys in course 'E' = (1200 x 12/100 ) - 800 x 14/100 ) = 144 - 112 = 32
Number of boys in course 'F' = (1200 x 13/100 ) - ( 800 x 14/100 ) = 156 - 112 = 44
Hence, number of boys in course 'C' and 'F' are same which is 44. - 1. How many girls are there in course C?

Explanation:
Correct Answer: 250
Explanation:
For course E,
Number of boys = ( 1200 x 12/100 ) - (800 x 14/100 ) = 144 - 112 = 32
Number of girls = 800 x 14/100 = 112
Required percentage = ( (112 - 32 )/32 ) x 100 = (80/32) x 100 = 250%
Correct Answer: A
Explanation:
As per first graph,
The number of students for course A = Total number of students x 20%
As per second graph,
The number of girls for course A = Total number of girls x 30%
Number of boys in course 'A' = The number of students for course A - The number of girls for course A
Number of boys in course 'A' = (1200 x 20/100 ) - ( 800 x 30/100 ) = 240 - 240 = 0
Number of boys in course 'C' = (1200 x 5/100 ) - (800 x 2/100) = 60 - 16 = 44
Number of boys in course 'E' = (1200 x 12/100 ) - 800 x 14/100 ) = 144 - 112 = 32
Number of boys in course 'F' = (1200 x 13/100 ) - ( 800 x 14/100 ) = 156 - 112 = 44
Hence, in course 'A' number of boys is minimum which is Zero.
Correct Answer: 3 : 4
Explanation:
As per first graph,
The number of students for course D = Total number of students x 20%
As per second graph,
The number of girls for course D = Total number of girls x 30%
Number of boys in course D = The number of students for course D - The number of girls for course D
Number of boys = ( 1200 x 35/100 ) - ( 800 x 30/100 ) = 420 - 240 = 180
Number of girls = 800 x 30/100 = 240
Since, required ratio = 180 : 240 = 3 : 4
Correct Answer: 11 : 9
Explanation:
As per first graph given in the question,
Number of people working in night shifts from Call Center Industry = Total number of people working in industries x 32%
Number of people working in night shifts from Call Center Industry = 40250 x 32/100 = 12880
As per second graph given in the question,
Then Number of females working in night shifts from Call Center Industry = Number of people working in night shifts from Call Center Industry x 45%
Number of women working in night shifts from Call Center Industry = 12880
x 45/100 = 5796
So, the number of men working from call center Industry = 12880 - 5796 = 7084
Hence, Required ratio = 7084 : 5796 = 11 : 9
Correct Answer: 26887
Explanation:
Number of men working in night shifts in different industries will be as below.
As per given graphs in question,
Number of total people working in night shifts in IT = 40250 x 12%
Number of men working in night shifts in IT = 40250 x 12% x (100% - 20% )
Number of men working in night shifts in IT = 40250 x 12% x 80%
? Number of men working in night shifts in IT = 40250 x (12/100) x 80/100
? Number of men working in night shifts in IT = 3864
Similarly,
Number of men working in night shifts in Sports = 80/100 x 18/100 x 40250 = 5796
Number of men working in night shifts in Call Center = 55/100 x 32/100 x 40250 = 7084
Number of men working in night shifts in Sales = 40/100 x 8/100 x 40250 = 1288
Number of men working in night shifts in Banking = 60/100 x 14/100 x 40250 = 3381
Number of men working in night shifts in Chemical Industries = 85/100 x 16/100 x 40250 = 5474
Hence, total number of men working in night shifts in different industries = 3864 + 5796 + 7084 + 1288 + 3381 + 5474 = 26887
