There were 132 adults enrolled in the Emma Computer School in 2021. ³₁₁ of the adults were men. Additional adults joined the computer school in 2022. 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 2022, how many women joined the school in that year?

	Men	Women
Before	36	96
Change	+ 3 u	+ 2 u
After	36 + 3 u	96 + 2 u

Fraction of adults who are women
= 1 - ³₁₁
= ⁸₁₁

Number of men at first
= ³₁₁ x 132
= 36

Number of women at first
= ⁸₁₁ x 132
= 96

Men who joined : Women who joined
3 : 2

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

36 + 3 u = 96 + 2 u
3 u - 2 u = 96 - 36

1 u = 60

Number of women who joined the school in that year
= 2 u
= 2 x 60
= 120

Answer(s): 120
