At a party,
25 of the people are children. The remaining group of people is divided into women and men in the ratio of 2 : 7. Each woman is given 2 keychains and each man is given 5 keychains.

36 u |
Number of keychains given away to men and children
= 35 u + 36 u
= 71 u
1 u = 355 ÷ 71 = 5
Number of less women than men
= 7 u - 2 u
= 5 u
= 5 x 5
= 25
