There were 217 adults enrolled in the Abi Swimming School in 2016. ³₇ of the adults were women. Additional adults joined the swimming school in 2017. For every 3 women who joined the swimming school, 2 men joined the swimming school. If there was an equal number of men and women in 2017, how many men joined the school in that year?

	Women	Men
Before	93	124
Change	+ 3 u	+ 2 u
After	93 + 3 u	124 + 2 u

Fraction of adults who are men
= 1 - ³₇
= ⁴₇

Number of women at first
= ³₇ x 217
= 93

Number of men at first
= ⁴₇ x 217
= 124

Women who joined : Men who joined
3 : 2

The number of men and women in the end is the same.

93 + 3 u = 124 + 2 u
3 u - 2 u = 124 - 93

1 u = 31

Number of men who joined the school in that year
= 2 u
= 2 x 31
= 62

Answer(s): 62
