[From: ] [author: ] [Date: 11-08-24] [Hit: ]
one marble from some other hat, and place both removed marbles to the third hat. Can we reach a situation where there are 7 marbles in each hat after some number of moves? If so, show the way. If not,......
Find the solution for the following: There are 3 hats with 11, 6, and 4 marbles, respectively. On a single move we can remove one marble from one of the hats, one marble from some other hat, and place both removed marbles to the third hat. Can we reach a situation where there are 7 marbles in each hat after some number of moves? If so, show the way. If not, provide argument why not?

-
hat 1 = 11 marbles
hat 2 = 6 marbles
hat 3 = 4 marbles

step 1 - take one marble each from hats 1 and 2 and place in hat 3 to get
hat 1 = 10 marbles
hat 2 = 5 marbles
hat 3 = 6 marbles

repeat step 1 to get
hat 1 = 9 marbles
hat 2 = 4 marbles
hat 3 = 8 marbles

step 2 - take one marble each from hat 1 and 3 and place in hat 2 to get
hat 1 = 8 marbles
hat 2 = 6 marbles
hat 3 = 7 marbles

in order to get 7 marbles in each hat all we would need to do is move just ONE marble from hat 1 to hat 2. but because we are moving 2 marbles at a time the numbers in the 3 hats will always be different and not the same
