The given table shows the number (in percent) of employees working in different departments of an organization. The table also shows the ratio of males and females and the ratio of employees living in city Z and employees living in city Y. The total number of employees in the organization are 80000.
How many employees of department A and C together are living in city Z?
Solution
Total number of employees = 80,000 Now percentage of employees in department A = 10%Â so number = 800 Now Number of employees living in city Z from department A =Â $$\frac{1}{10}\times\ 8000\ =\ 800$$ Now number of employees in department C =$$\frac{12}{100}\times\ 80000\ =\ 9600$$ Now number of employees in city Z from department C = $$\frac{5}{6}\times\ \ 9600\ =8000$$ So total we get 8000+800 = 8800
