If Bob gives 1/4th of his marbles to Joe, Bob will have the same number of marbles as Joe has. If Joe gives 1/4th of his marbles to Bob, Bob will have three times the number of marbles that Joe has. How many marbles does Bob have?

b - 1/4 b = j + 1/4 b

b = j + 1/2 b

1/2 b = j

b = 2j

b + 1/4 j = 3 ( j - 1/4j)

b + 1/4 j = 3j - 3/4 j

b = 3j - j

b = 2j

Bob has twice as many marbles as Joe. But we cannot determine EXACTLY how many marbles Bob has.....could be something like

60:30 or 80:40 or 92:46 etc .....
