उत्तर
In mixture E,
The number of blue containers = 6
The number of white containers = 1
∴ Ratio of blue and white = `6/1` = 6
In mixture F,
The number of blue containers = 4
The number of white containers = 2
∴ Ratio of blue and white = `4/2` = 2
Clearly, mixture F would be lighter shade, since for lighter shade white container should be equal or more than or nearest number of blue container.
