Question Of March:

A company runs two factories in the same town. Between the two factories the company employs 225 workers.

• One week, 1/5 of the workforce at one of the factories was transfered across town to the other factory.
• Then, the next week, 1/4 of the then-present workers at one of the factories was transfered to the other factory.
• Finally, the week after that, 1/3 of the workers then stationed at the Westside factory were transfered to the Eastside factory.
• After this last transfer, the difference between the two workforces was 21 workers.

How many workers were originally stationed at the Westside factory?

The answer will be posted in April 3rd.
