The number of men in a park was
79 that of the women. There were 60 more women than men. After some men left the park, the number of women in the park was five times the number of the remaining men. How many men left the park?

7 u |
9 u |

- ? |

After |
1x3 =
3 u |
3x3 =
9 u |
The number of women remain unchanged. Make the number of women the same. LCM of 9 and 3 is 9.
Number of more women than men
= 9 u - 7 u
= 2 u
2 u = 60
1 u = 60 ÷ 2 = 30
Number of men who left the park
= 7 u - 3 u
= 4 u
= 4 x 30
= 120
Answer(s): 120
