(2) states "Each played less than 50 games", it doesn't say the sum of the games is less than 50. And not sets, but games.
When dealing with DS questions, you have to work out the answer solely based on the question stem and the info in a specific statement when considering it alone.
I think you mix up sets with games. It is about the third set, and the number of games each played. How are 1 and 3 relevant?[/quote]
No Dear I Haven't Mixed up ! Not at all
If each played less than 50 games then out of those 50 lets say federer one x and the other guy one y, then will the sum of x & y be less than 50 or not ?
and in the last set the winner won exactly two consecutive games more than the loser ! ans their sum has to be a perfect square !.
Now if by solving the first statement i know the values i can just check it in the second statement and find if i can get the anwser or not ! Because you are forgetting the fact that both statements have to give the same answer ! i can either solve the second statement and waste time or i can use the answer i got already and test it in it. because if at all second statement is sufficient than it will give the same answer . now that is a FACT ! and it does
By mistake i did use games ans sets interchangeably that was understandble
