The document states that initially the ratio of men to women at a gathering was 5:7. After 60 men left, the ratio became 1:2. To determine the original number of men, it is shown that if the original number of women was 7u, then the original number of men was 5u. Subtracting 60 men from 5u gives the new ratio equation, which is solved to find the original number of men was 200.
