Question
What is the average number of male employees working in
company B and C together? Study the following information carefully and answer the questions given below: There are three companies i.e. A, B and C. Total number of employees working in company A is 880. The number of male employees working in company C is 220. The number of male employees working in company C and B together is 760. Number of male employees working in company B is 20% more than the number of female employees working in company A. The ratio of number of male employees to female employees working in company C is 11:9, respectively. Total number of female employees working in all companies together is 930.Solution
Number of male employees working in company B = 760 – 220 = 540 Number of female employees working in company A = 540 x (100/120) = 450 Number of female employees working in company C = 220 x (9/11) = 180 Number of female employees working in company B = 930 – (450 + 180) = 300 Number of male employees working in company A = 880 – (540 + 220) = 120 
Required average = (540 + 220)/2 = 380
