At a party,
13 of the people are children. The remaining group of people is divided into men and women in the ratio of 2 : 3. Each man is given 3 magnets and each woman is given 6 magnets.

36 u |
35 u |
Number of magnets given away to women and children
= 36 u + 35 u
= 71 u
1 u = 142 ÷ 71 = 2
Number of less men than women
= 6 u - 4 u
= 2 u
= 2 x 2
= 4
