Question

150 people attend a concert. There were 30 more adults than children at the concert. There were 20 more men than women. What was the ratio of the number of men to the number of women to the number of children?

Answer 1

Answer:

11:7:12

Step-by-step explanation:

take x to be number of women

Total= 150

adults=(x+x+20)= 2x+20

children=(2x+20-30)= 2x-10

men =x+20

women=x

find the value of x

2x-10+x+20+x=150

2x+x+x+20-10+=150

4x+10=150

4x=150-10

4x=140. divide both sides by 4

x=35

thus.

men=(35+20)=55

women=35

children=70-10=60

ratio= 55:35:60.

simplify= 11:7:12
