The number of women in a park was
79 that of the men. There were 120 more men than women. After some women left the park, the number of men in the park was five times the number of the remaining women. How many women left the park?
|
Women |
Men |
Before |
7 u |
9 u |
Change |
- ? |
|
After |
1x3 = 3 u |
3x3 = 9 u |
The number of men remain unchanged. Make the number of men the same. LCM of 9 and 3 is 9.
Number of more men than women
= 9 u - 7 u
= 2 u
2 u = 120
1 u = 120 ÷ 2 = 60
Number of women who left the park
= 7 u - 3 u
= 4 u
= 4 x 60
= 240
Answer(s): 240
