Problema Solution
A 720ml container holds a mixture red, yellow and white paint in a 5:3:12 ratio. How much more red paint than yellow is present in the mixture?
Answer provided by our tutors
5x+3x+12x=720
20x=720
x=720/20
x=36
So red = 180ml
yellow = 108 ml
white = 432 ml
So there is 180-108 = 72 ml of more red than yellow
