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.
You can, for example never foretell what any one man will do, but you can say with precision what an average number will be up to!
