There were 297 adults enrolled in the Xandra Gym School in 2022. ⁴₁₁ of the adults were men. Additional adults joined the gym school in 2023. For every 4 men who joined the gym school, 3 women joined the gym 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	108	189
Change	+ 4 u	+ 3 u
After	108 + 4 u	189 + 3 u

Fraction of adults who are women
= 1 - ⁴₁₁
= ⁷₁₁

Number of men at first
= ⁴₁₁ x 297
= 108

Number of women at first
= ⁷₁₁ x 297
= 189

Men who joined : Women who joined
4 : 3

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

108 + 4 u = 189 + 3 u
4 u - 3 u = 189 - 108

1 u = 81

Number of women who joined the school in that year
= 3 u
= 3 x 81
= 243

Answer(s): 243
