The line chart below shows the number of employees and the number of male employees in four different companies.

Note 1: Total number of employees = Number of (male + female) employees
Note 2: Total number of male employees = number of male employees in senior post + number of male employees in non-senior post
Note 3: Total number of female employees = number of female employees in senior post + number of female employees in non-senior post

Important for :
1
The total numbers of male employees in all the companies together is what percentage of the total number of employees in all the given companies together?
» Explain it
B
Total number of male employees in senior post = (244 + 210 + 178 + 184) = 816

Total number of male employees in non senior post = (728 + 1025 + 692 + 900) = 3345

Total number of employees = (1743 + 2126 + 1584 + 1872) = 7325

 Reqd.% = 3345 + 816 × 100 = 56.8% 7325

Hence, option B is correct.
2
Find the difference between the total number of males in non-senior post in all the companies together and the total number of females in non-senior post in all the companies together.
» Explain it
D
Total number of male employees in non senior post = (728 + 1025 + 692 + 900) = 3345

Total number of female employees in non senior post = (617 + 644 + 516 + 625) = 2402

Required difference = (3345 – 2402) = 943

Hence, option D is correct.
3
Find the ratio of the total number of male employees in senior post in all the companies together to the total number of female employees in senior post in all the companies together.
» Explain it
C
Total number of employees = (1743 + 2126 + 1584 + 1872) = 7325

Total number of male employees in senior post = (244 + 210 + 178 + 184) = 816

Total number of male employees in non senior post = (728 + 1025 + 692 + 900) = 3345

Total number of female employees in non senior post = (617 + 644 + 516 + 625) = 2402

Total number of female employees in senior post = (7325 – 816 – 3345 – 2402) = 762

Required ratio = 816 : 762 = 136 : 127

Hence, option C is correct.

C
Total number of employees = (1743 + 2126 + 1584 + 1872) = 7325

Total number of male employees in senior post = (244 + 210 + 178 + 184) = 816

Total number of male employees in non senior post = (728 + 1025 + 692 + 900) = 3345

Total number of female employees in non senior post = (617 + 644 + 516 + 625) = 2402

Total number of female employees in senior post = (7325 – 816 – 3345 – 2402) = 762

 Reqd. average = 2402 + 762 = 791 4

Hence, option C is correct.
5
Find the difference between the number of male employees in senior post in TCS and HCL together and the number of female employees in senior post in Wipro and Infosys together.
» Explain it
B
Male employees in senior post in TCS and HCL together = (244 + 210) = 454

Female employees in senior post in Wipro = (1584 – 178 – 692 – 516) = 198

Female employees in senior post in Infosys = (1872 – 184 – 900 – 625) = 163

Required difference = 454 – (198 + 163) = 93

Hence, option B is correct.
