| Before |
3 u + 134 |
1 u + 134 |
394 |
| Change |
- 134 |
- 134 |
|
| 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 = 394
1 u = 394 ÷ 2 = 197
Number of men in the end
= 3 u
= 3 x 197
= 591
Number of men that left
= 268 ÷ 2
= 134
Number of men at first
= 591 + 134
= 725
Answer(s): 725
