Step-by-step explanation
The answer would be 162 total number of employees.
The steps would be to cross multiply and divide then add the number of women to the number you get after cross multiply and divide.
4 =x
5 =90
so now you multiply 4 and 90 you should get 360 then take 360 and divide by 5 and you get 72. the number of women was already given so there are 90 women ,then we just got the number of men which was 72 then you just add 90+72 and there is 162 employees.
Hopefully this helps
