Three friends Ade, Ben and Cade have 9 marbles in front of them. Their weights are as follows:
154, 16, 19, 101, 10, 17, 13, 46 and 22 grams.
Each of the three friends takes 3 marbles. Ade's bunch weighs precisely twice as much as Bill's bunch.
What is the total weight in Cade's bunch?

Exactly so. Good point.
I realized this as soon by the time I got to listing the mod3 values, but I had already typed out everything so far, so I just included it all.
