The number of men in a arcade was
710 that of the women. There were 150 more women than men. After some men left the arcade, the number of women in the arcade was five times the number of the remaining men. How many men left the arcade?

The number of women remain unchanged. Make the number of women the same. LCM of 10 and 5 is 10.
Number of more women than men
= 10 u - 7 u
= 3 u
3 u = 150
1 u = 150 ÷ 3 = 50
Number of men who left the arcade
= 7 u - 2 u
= 5 u
= 5 x 50
= 250
Answer(s): 250
