At first, there were 404 more men than women at the safari park. By 3 p.m., a total of 270 men and women left the safari park. There were as many men as women who left the safari park. In the end, there were 3 times as many men as women who remained behind. How many men were at the safari park at first?

Difference |
Before |
3 u + 135 |
1 u + 135 |
404 |
Change |
- 135 |
- 135 |
|
After |
3 u |
1 u |
2 u |
Since there was the same number of women and men that left, the difference between the number of women and men remains unchanged.
2 u = 404
1 u = 404 ÷ 2 = 202
Number of men in the end
= 3 u
= 3 x 202
= 606
Number of men that left
= 270 ÷ 2
= 135
Number of men at first
= 606 + 135
= 741
Answer(s): 741
