Question

turquoise paint is made by mixing blue, green and yellow paint in the ratio 2.5 : 1.4 : 0.1 . how much of each colour is needed to make 1.5 litres of turquoise paint? write answers in the same order as the ratio (eg, blue, green, then yellow)​

Answer 1

Answer: Blue color = 937.5 ml

green color = 525 ml

Yellow color= 37.5 ml

Explanation:

Let the quantity of all kinds of paint required to make turquoise paint be 2.5 x(blue), 1.4 x( green), 0.1 x.(yellow).

Total turquoise color required =2.5x+1.4x+0.1x

`\Rightarrow (2.5+1.4+01)x=1.5\\\\\Rightarrow\ 4x = 1.5\\\\\Rightarrow x=(1.5)/(4)\\\\\Rightarrow\ x=0.375` = 1.5 liters [given]

Blue color = 2.5 x 0.375 = 0.9375 liters = 937.5 ml [1 liter = 1000 ml]

green color = 1.4 x 0.375= 0.525 l = 525 ml

Yellow color= 0.1 x 0.375= 0.0375 =37.5 ml
