Hello !!
For you answer this question, you only need make use of this method below. See the resolution.
M(3) = 0, 3, 6, 9, 12, 15, 18, 21, 24, 27, 30, 33...
With this information, we have :
24 + 27 + 30
= 20 + 20 + 30 + (7 + 4)
= 40 + 30 + (7 + 4)
= 70 + 11
= 81
Therefore, 30 is the largest number.
