Question

Pink paint is made by mixing white paint and red paint in the ratio 5 : 3. 32 litres of pink paint are made. How much white paints are used?

Answer 1

20 liters of white paint, 12 liters of red paint

Explanation:

Let w = liters of red paint and r = liters of red paint

`(w)/(r) = (5)/(3)`

`w = (5)/(3) r`

`w + r = 32`

`(5)/(3) r + r = 32`

`(8)/(3) r = 32`

`r = 12`

`w = 20`
