There were 154 adults enrolled in the Risa Dancing School in 2022.
37 of the adults were women. Additional adults joined the dancing school in 2023. For every 3 women who joined the dancing school, 2 men joined the dancing school. If there was an equal number of men and women in 2023, how many men joined the school in that year?

Change |
+ 3 u |
+ 2 u |
After |
66 + 3 u |
88 + 2 u |
Fraction of adults who are men
= 1 -
37 =
47 Number of women at first
=
37 x 154
= 66
Number of men at first
=
47 x 154
= 88
Women who joined : Men who joined
3 : 2
The number of men and women in the end is the same.
66 + 3 u = 88 + 2 u
3 u - 2 u = 88 - 66
1 u = 22
Number of men who joined the school in that year
= 2 u
= 2 x 22
= 44
Answer(s): 44
