Paint Mixing: Whose Paint Will Be Darker?

Which artist's gray paint will be darker, Greg's or Tom's?

Final answer:

The gray paint will be darker in Tom's case as he uses a larger proportion of black paint in his mixture than Greg.

Explanation:

The density of black paint in the mix determines the darkness of the gray paint. For Greg, the proportion of black paint is 3 out of 11 parts (because 3 parts black plus 8 parts white makes 11 parts in total), while for Tom, the proportion of black paint is 4 out of 13 parts (4 parts black plus 9 parts white gives a total of 13 parts). Fractionally, Greg's ratio is approximately 0.27 and Tom's is around 0.31. Therefore, the paint will be darker in Tom's case as he uses a larger proportion of black paint in his mixture.
