At first, there were 375 more men than women at the bird park. By 4 p.m., a total of 236 men and women left the bird park. There were as many men as women who left the bird park. In the end, there were 4 times as many men as women who remained behind. How many men were at the bird park at first?

Difference |
Before |
4 u + 118 |
1 u + 118 |
375 |
Change |
- 118 |
- 118 |
|
After |
4 u |
1 u |
3 u |
Since there was the same number of women and men that left, the difference between the number of women and men remains unchanged.
3 u = 375
1 u = 375 ÷ 3 = 125
Number of men in the end
= 4 u
= 4 x 125
= 500
Number of men that left
= 236 ÷ 2
= 118
Number of men at first
= 500 + 118
= 618
Answer(s): 618
