After winning 80 percent of the first 40 games it played, Team A lost all the remaining games it played. How many total games did Team A play?
(1) Team A lost all of its games against Team B, which won 75 percent of its total games.
(2) Team A lost exactly 1/3 of all the games it played.

After winning 80 percent of the first 40 games it played, Team A lost all the remaining games it played. How many total games did Team A play?
Team A lost 0.2*40=8 of the first 40 games and all the remaining games, say x. So, total games lost is 8+x and total games played is 40+x.
(1) Team A lost all of its games against Team B, which won 75 percent of its total games. Clearly not sufficient.
(2) Team A lost exactly 1/3 of all the games it played --> 8+x=1/3*(40+x), only one unknown, hence we can solve for it. Sufficient.
Answer: B.
Hope it's clear.

Hi,
I used a tabular format as mentioned below
- - 40 Games - - X-40 Games
Won - - 32 -------0
Lost- - 8 ---------X-40
Statement 1 : We have no clue if Team A played B C D E hence insufficient
Statement 2 : X/3 = 8 + X - 40
Sufficient
Thus B
Hope this helps
