The number of women in a funfair was
1115 that of the men. There were 320 more men than women. After some women left the funfair, the number of men in the funfair was five times the number of the remaining women. How many women left the funfair?

- ? |

After |
1x3 = 3 u |
5x3 = 15 u |
The number of men remain unchanged. Make the number of men the same. LCM of 15 and 5 is 15.
Number of more men than women
= 15 u - 11 u
= 4 u
4 u = 320
1 u = 320 ÷ 4 = 80
Number of women who left the funfair
= 11 u - 3 u
= 8 u
= 8 x 80
= 640
Answer(s): 640
