13 of the people are children. The remaining group of people is divided into men and women in the ratio of 3 : 5. Each man is given 2 keychains and each woman is given 4 keychains.

Number of keychains given away to women and children
= 20 u + 20 u
= 40 u
1 u = 480 ÷ 40 = 12
Number of less men than women
= 5 u - 3 u
= 2 u
= 2 x 12
= 24
Answer(s): 24
