The number of men in a cinema was
1115 that of the women. There were 240 more women than men. After some men left the cinema, the number of women in the cinema was five times the number of the remaining men. How many men left the cinema?

Before |
11 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 - 11 u
= 4 u
4 u = 240
1 u = 240 ÷ 4 = 60
Number of men who left the cinema
= 11 u - 3 u
= 8 u
= 8 x 60
= 480
Answer(s): 480
