Factory Qn - Mr Shew

Dear Sunny,

I came across an interesting problem sum while revising Maths with Alden:

There are 500 male and 200 female employees in factory A. There are 400 male and 600 female employees in factory B. Some employees are transferred from factory A to factory B. After the transfer, the number of male employees is the same as the number of female employees in factory B and the number of male employees is twice the number of female employees in factory A. How many female employees were transferred from factory A to factory B? (Answer: 100)

Could you advise other method besides Model Drawing to solve this question? The question is taken from math456.com P5 Maths CAs and Sas for Top Primary Schools.
