Question 150

# What is the total number of employees working in the Management Department ?

Solution

Total number of employees = 750

Males = $$\frac{8}{15} * 750$$ = 400

Females = 750 - 400 = 350

Females in Mgmt department = $$\frac{16}{100} * 350$$ = 56

Males in HR department = $$\frac{32}{100} * 400$$ = 128

Females in recruit department = $$\frac{1}{5} * 350$$ = 70

Males in Mgmt department = $$\frac{3}{2} * 56$$ = 84

Total number of employees working in the Management department = 140
