The number of men in a laser tag park was
1315 that of the women. There were 120 more women than men. After some men left the laser tag park, the number of women in the laser tag park was five times the number of the remaining men. How many men left the laser tag park?

Before |
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 = 120
1 u = 120 ÷ 2 = 60
Number of men who left the laser tag park
= 13 u - 3 u
= 10 u
= 10 x 60
= 600
Answer(s): 600
