When asked about the results of their blitz games, Bobby Fischer said, "We played the same number of games. Larry won two-thirds of his games and I lost only one of mine."
Larry Evans added, 'We didn't draw any games and between us the two of us won three-quarters of our games."
How many games did Larry Evans and Bobby Fischer play?
Originally posted by petrovitchIf we let Lw and Lp be the number of games Larry won and played, respectively; and let Bw and Bp be the number of games Bobby won and played respectively; then we have the following equations.

How many games did Larry Evans and Bobby Fischer play?
1. Lw = (2/3)Lp
2. Lp = Bp
3. Bw = Bp-1
4. Lw + Bw = (3/4)(Lp + Bp)
Together, these entail that Lp = Bp = 6.
So each played in 6 games with Bobby going 5-1 and Larry going 4-2.
However, if your question is how many distinct games this comprises, then I think there is not enough information. For instance, there could have been as many as 12 distinct games or as few as 9 (since, given the information, Larry and Bobby could have played against each other in as many as 3 of the games).

This assumes that you are limiting the problem to only games between the two players. That isn't explicity stated.
At any rate, the opening problem statement is ambiguous. Is he asking for Lp (which also equals Bp)? Is he asking for the value of (Lp + Bp)? Or is he asking for the number of distinct games (for which, again, there's not enough information)? Or is he asking for the number of games where the two played each other (for which there's also not enough information)?
