13 of the people are children. The remaining group of people is divided into women and men in the ratio of 2 : 3. Each woman is given 2 keychains and each man is given 4 keychains.

Number of keychains given away to men and children
= 24 u + 30 u
= 54 u
1 u = 432 ÷ 54 = 8
Number of less women than men
= 6 u - 4 u
= 2 u
= 2 x 8
= 16
Answer(s): 16
