Johnny vs. Vinny
As brothers, these two are competitive in every aspect of life. Just check out some of my other puzzles, and you'll see my brothers in action.
Today is a classic Marble Battle! The brother's played a series of 3 games:
The Game Series Summary
Round 1 Johnny and Vinny each had a certain number of playing marbles. Johnny lost a game to Vin and had to give Vin half of his marbles.
Round 2 In the second game, Vin lost and had to give three-fourths of his marbles to Johnny, who now had thirty marbles.
Round 3 Finally, the two finished their third game. Vinny won and acquired some of Johnny's marbles.
Score Board At this point, each brother had exactly the number of marbles he had started with, and Johnny had twice as many marbles as Vinny.
