Question

45% of the population of a town are men and 35% are women. If the number

of children is 30,000, find the number of men.

Answer 1

67,500

Explanation:

20 percent of the population is children. 45 percent is men. If children population is 30000, you multiply by 2 to get 40 percent. That means that if men were 40 percent, men population would be 60000. When you add another 5 percent to get 45 percent, it makes 67500 men.

Answer 2

67,500 men

Explanation:

Percent of children = 20% (.2)

30,000 x 5 = 150,000 (Total pop.)

150,000-30,000 = 120,000 (Pop. minus children)

.35 (Percent of women) x 150,000 =52,500

120,000-52,500 = 67,500
