Sandra is playing in a tennis doubles tournament. How many years old or younger must her partner be?

(1) The rules say that the average age of the pair of players on each side must be ten years old or younger.

(2) Sandra is eight years old.

(1) If there are 2 players A and B and if we add their ages and divide by 2, we should get at least 10. So, the minimum value of combined ages of 2 players can be 20. But this is NOT SUFFICIENT to answer the question.

(2) Sandra is 8 years old, but we don't know about the rules for ages. So, (2) is also NOT SUFFICIENT.

Combining (1) and (2), we get Sandra is 8 years, so her partner's age should be 20 - 8 = 12 years old

[spoiler]The correct answer is (C).[/spoiler]

S, P are ages.
what is absolute value of S-P is the question.

(1) The rules say that the average age of the pair of players on each side must be ten years old or younger.

S+P <20

No info about any of their ages. hence INSUFF

(2) Sandra is eight years old.
No info about P. hence INSUFF

combining:
S+P<20
S=8
hence P <12
So S-P can be maximum of 4. which means P can be from 4 to 12 any number.

Hence INSUFF

pick E.

But why is the absolute value wrong?

The meaning of the phrase "How many years old or younger" is "the maximum possible age" here.

Is it so?

How many years old or younger must her partner be
I felt it ambiguous, because of "must" in the question.

well you have a point, would you like to make a circle out of it? :lol:


Is something ambiguous in this?

If x ≤ n. What is the maximum n?

NO.. There is nothing ambiguous in this. Because, it clearly asks for maximum n.

But, the question doesnt say, "At the max, how older/younger can her partner be"
