Question

The ratio of the number of cars to dolls in a toy store is 3/20 . The ratio of the number of male dolls to the number of female dolls is 3:5 There are 500 female dolls. How many toys are there?

Answer 1

800 dolls

Explanation:

Step one:

given data

we are told that the ratio of the number of male dolls to the number of female dolls is 3:5 , i.e male dolls to female dolls is 3 to 5

given that there are 500 female dolls, let the number of male dolls be x

Step two:

3/5= x/500

cross multiply we have

3*500=5x

1500=5x

divide both sides by 5

x=1500/5

x=300

hence there are 300 male dolls

The total dolls is 300+500= 800 dolls
