The ratio of men to women = 3:1

Number of committee members = 20

number of men in the committee = $\; \frac{3}{4} \times 20 = 15$

Number of women in the committee = $\; \frac{1}{4} \times 20 = 5$

New ratio = 3:2, and let the number of women to be added to make the ratio 3:2 be x

3:2 = 15:5+x

$\; \frac{3}{2} = \; \frac{15}{5 + x}$

15 + 3x = 30

3x = 30 - 15 = 15

x = $\; \frac{15}{3}$ = 5

Therefore, the number of women to be added to make the ratio of men to women 3:2 = 5.
