Solution
In mixture C,
The number of blue containers = 3
The number of white containers = 3
∴ Ratio of blue and white = `3/3` = 1
In mixture D,
The number of blue containers = 2
The number of white containers = 5
∴ Ratio of blue and white = `2/5` = 0.4
Clearly, mixture D would be lighter shade, since for lighter shade white container should be more than blue container.
