Common Explanation:
References:
V won both the matches against U.
Inference:
Studying the information carefully we can say that V and U were in same group let’s says that Group A. And we also know that Q, U, W, V were the four players who qualifed for the semifinal so we can also say that Q and W were in second group let’s say that Group B.

Group B

W/Q 


Number of matches won 




References:
Each player of each group had a different number of wins.
P and W won the same number of matches.
R lost all of his matches against all the other players except S, who atleast one match against each of the other players except one.
Inference:
Using the given information we can say that R and S belongs to Group B and P and T belongs to Group A its because P and w can’t be in the same group and R and S must go together. As it is given that R won only against S so he has only one point.

Now, In a group each player had to play twice against each of the other players. So the total number of matches that can be played in each group are equal to 12. And the winning combinations given that Each player of group had a different number of wins can only be
A  ( 6 4 2 0 )
B ( 6 3 2 1 )
C ( 5 4 2 1 )
D ( 5 4 3 0 )
In all of the combinations only B and C can fit in Group B. But we know that W and P have same number of wins so only combination B and D fits into our requirements.

But U cannot have 5 wins in Group A because he lost both of his matches to V.
Therefore the final scorecard is as follows
