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 : 7. Each man is given 2 magnets and each woman is given 3 magnets. Each accompanying child receives 5 magnets. Given that only 348 magnets are given away to women and children, how many less men are there than women?

8 u |
42 u |
45 u |
Number of magnets given away to women and children
= 42 u + 45 u
= 87 u
1 u = 348 ÷ 87 = 4
Number of less men than women
= 14 u - 4 u
= 10 u
= 10 x 4
= 40
Answer(s): 40
