The number of men in a theme park was
1315 that of the women. There were 140 more women than men. After some men left the theme park, the number of women in the theme park was five times the number of the remaining men. How many men left the theme park?

13 u |
15 u |
Change |
- ? |
|
After |
1x3 = 3 u |
5x3 = 15 u |
The number of women remain unchanged. Make the number of women the same. LCM of 15 and 5 is 15.
Number of more women than men
= 15 u - 13 u
= 2 u
2 u = 140
1 u = 140 ÷ 2 = 70
Number of men who left the theme park
= 13 u - 3 u
= 10 u
= 10 x 70
= 700
Answer(s): 700
