What is the ratio of the number of females in the HR and Accounts department together to the number of males in the same department together?

Solution:
(Number of females in HR and Accounts) : (Number of males in HR and Accounts)
= {(65100×360)+(35100×220)}       :{(35100×360)+(65100×220)}
= (234 + 77) : (126 + 143)
= 311 : 269
