(1) Team A lost all of its games against Team B, which won 75 percent of its total games.
(2) Team lost exactly 1/3 of all the games it played.
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.
