There were 231 adults enrolled in the Jean Computer School in 2016. ³₇ of the adults were men. Additional adults joined the computer school in 2017. For every 3 men who joined the computer school, 2 women joined the computer school. If there was an equal number of women and men in 2017, how many women joined the school in that year?

	Men	Women
Before	99	132
Change	+ 3 u	+ 2 u
After	99 + 3 u	132 + 2 u

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

Number of men at first
= ³₇ x 231
= 99

Number of women at first
= ⁴₇ x 231
= 132

Men who joined : Women who joined
3 : 2

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

99 + 3 u = 132 + 2 u
3 u - 2 u = 132 - 99

1 u = 33

Number of women who joined the school in that year
= 2 u
= 2 x 33
= 66

Answer(s): 66
