• There are ten boxes containing 4, 8, 27, 31, 34, 35, 44, 45, 51, and 59 balls of either red, or blue, or green in color.
• Some boxes contain only red balls, some boxes contain only blue balls, and remaining boxes contain only green balls.
• None of the boxes contain balls having more than one color.

One salesman sold only one box out of them and he declared, "I have the same number of red, blue, and green balls left over."

Which box is sold out?

(In reply to soln by Steven Lord)

That gives four possibilities: remove 4, 35, 44, 59
