Guys  I am consistently getting these type of questions wrong. Can someone please explain the step by step approach? Even though I answered it wrong, I think I know why. Team won 80% of first 40 games => Win = 32 Lost/ Tie 8 out of first 40. and lost all after wards. So total Win (32) + Lost (x) + Tie/ Lost (8) 1) Team B won 75% of games it played and Team A lost all against it. Do not know how many teams are there over all. How many games each team plays agains another. 2) Team lost 1/3 of the game. **HERE I MADE MISTAKE** lost =1/3 NOT EQUALs TO 2/3 won because there could be tie in some of the 8 games out of first 40. So, not sufficient. Hence E.

Answer to this question cannot be E, it's B. After winning 80 percent of the fi
rst 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   X40 Games Won   32 0 Lost  8 X40 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

Statement 2 is sufficient because we know how many it won and how many it lost.
