At first, there were 430 more men than women at the safari park. By 3 p.m., a total of 248 men and women left the safari park. There were as many men as women who left the safari park. In the end, there were 6 times as many men as women who remained behind. How many men were at the safari park at first?

| Before |
6 u + 124 |
1 u + 124 |
430 |
| Change |
- 124 |
- 124 |
|
| After |
6 u |
1 u |
5 u |
Since there was the same number of women and men that left, the difference between the number of women and men remains unchanged.
5 u = 430
1 u = 430 ÷ 5 = 86
Number of men in the end
= 6 u
= 6 x 86
= 516
Number of men that left
= 248 ÷ 2
= 124
Number of men at first
= 516 + 124
= 640
Answer(s): 640
