Colour A is made by mixing red, blue and green in the ratio 2 : 6 : 7. Colour B is formed by mixing red, blue and green in the ratio 3 : 5 : 4. If 5 parts of colour A are mixed with 4 parts of colour B, what is the ratio of liquids x, y and z in the resulting mixture?
Explanation:
Ratio of volumes = 15 : 12 = 5 : 4
We have to mix in the ratio 5 : 4.
Final ratio x : y : z = (2 + 3) : (6 + 5) : (7 + 4) = 5 : 11 : 11
Hence, option (d).
