There were 253 adults enrolled in the Ivory Computer School in 2022. ³₁₁ of the adults were men. Additional adults joined the computer school in 2023. 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 2023, how many women joined the school in that year?

	Men	Women
Before	69	184
Change	+ 3 u	+ 2 u
After	69 + 3 u	184 + 2 u

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

Number of men at first
= ³₁₁ x 253
= 69

Number of women at first
= ⁸₁₁ x 253
= 184

Men who joined : Women who joined
3 : 2

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

69 + 3 u = 184 + 2 u
3 u - 2 u = 184 - 69

1 u = 115

Number of women who joined the school in that year
= 2 u
= 2 x 115
= 230

Answer(s): 230
