Question

A toy store received a large shipment of toy race cars. The cars come in blue and red. Because the red cars are more popular, the toy store wanted the ratio of red cars to blue cars to be 3:2. If total number of cars received was 40, then how many of the cars were red?

Answer 1

24 cars

Explanation:

Given

`Red:Blue = 3:2`

`Cars = 40`

Required

Determine the number of red cars

Number of red cars is calculated using:

`Red\ Cars = (Red\ Ratio)/(Total\ Ratio) * Cars`

`Red\ Cars = (3)/(3 + 2) * 40`

`Red\ Cars = (3)/(5) * 40`

`Red\ Cars = (3 * 40)/(5)`

`Red\ Cars = (120)/(5)`

`Red\ Cars = 24`
