Team A won 30 percent of the first 50 games it played which is 15.

(1) Team A won 11 of the last 12 games it played

One knows that 15 of the first 50 matches were won and that every match after was won. However, without knowing when the loss occurred from the 12 games mentioned in this statement it is impossible to deduce how many of these wins form part of the 15 wins from the initial 50 games and how many form part of the matches which occurred after. The total wins could be any number between 16 to 26.

INSUFFICIENT

(2) Team A won 14 of the first 48 games it played

This statement shows that in the final two matches of the intial 50, Team A won 1 and lost 1. However, no information is provided with which one can solve the number of games Team A won in total.

INSUFFICIENT

(1+2)

Usisng Statement 2's info that 1 of the last 2 games of the initial 50 was a loss, together with Statement 1's info that 11 of the last 12 matches were wins - one narrows down the possible total wins to either be 25 or 26. However, without further info it is impossible to solve which of the two cases it is.

INSUFFICIENT

ANSWER E

Given - After winning 30 percent of the first 50 games it played, team A won all the remaining games it played.
from first 50 (15 winning, 35 Loses)
To find - How many total games did Team A win?

(1) Team A won 11 of the last 12 games it played
  Not sufficient   because what if these 12 include some of first 50 so we are not sure.

(2) Team A won 14 of the first 48 games it played
From this we are able to deduce, from remaining 2 one is loss and one is win. But what about remaining games after 50? No information?
  Not sufficient

Combining both i think we cant answer this 
see 1st says won 11 out of last 12. difference of 1 game and that difference is we can guess for game 49 or 50 but again here there inconsistency in data.
What if in some of the games earlier 48 were winning streaks? So this is also a possibility.

Answer is E

Hi guys. Can anyone please tell me where I'm going wrong with my reasoning please?

Statement 1 : Team A won 11 of the last 12 games.
It also states that team A won all of the remaining games after the first 50. So it must have played 11 additional games.
So 15 games from the first 50 games + 11 games = 26 games.

Sufficient. I chose option A for this reason

I believe the correct answer is C. The prompt states that the player won 30 percent of the first 50 games and 100 percent of the remaining games. This means that out of the first 48 games, we know the player won at least 14 games. The two remaining games are the 49th and 50th, and we know that one of these was won by Team A. Since the remaining games outside of the first 50 were all won, and the second prompt mentions that the player won 11 of the last 12 games played, we can infer that only 10 additional games have been played

HowCanIDoThis · Answer

I had the same misunderstood (and the same answer) as yours. But when I re-read the question, the statement (1) only reveals the number of wins in  the last 12 .  The last 12  here can include some of the games in the first 50 & the additional ones. This means we cannot infer that they have played 11 additional games.
"Team A won all of the remaining games after the first 50" is not a defining factor in calculating the number of games played, as it only tells us that they played more than 50 games.
