I assessed it this way:

Statement 1: L team has 8 points, that is 2 wins and 2 draws.But there is no information about the other team's scores. Insufficient.

Statement 2. Total points is 23. This can be arrived at by many combination of scores. no information about the distribution of score is given. Insufficient.

Combining 1 & 2:
L has 8 points out of 23. i.e the remaining teams distribute 15 points among themselves.

Suppose if all matches were tied then the score would have been 2*10=20 and suppose all matches were win matches 3*10=30.

Then to score 23 points we would need 3 matches to be won in total and seven drawn matches.(If u can draw a table with this combination)

Wins Draws Total
10 0 30
9 1 29 and so on

L has won 2, then only 1 other team could have won this match.However, all the teams would have scored less than 8.

Sufficient L is the leader.

Hi gmmattesttaker2,

Vinay1983 did a nice job of breaking down the possibilities (and it's exactly how I would have done it); this approach serves as a great way to tackle certain Quant questions.

This DS question is a bit tougher than the typical GMAT DS question that would test the concept, but it serves as a good example of what's called "limited options." In these types of questions, STARING is NOT an option. To solve this question quickly, you MUST take some notes and "map out" the possibilities.

For example, since there are 5 teams, there are ONLY 10 total games played (you have to take the time to figure that out)

With each game...
It's either a Win for one and a Loss for another = 3 + 0 = 3 pts
OR it's a Tie for one and a Tie for another = 1 + 1 = 2 pts

You have to also take the time to figure that out.

Be prepared to figure things out on Test Day. It's one of the skills that helps to lead to high scores on the GMAT.
