The key here is to recognize that the question does NOT state that x and y are integers
Given: -3 < y < x < 6
B) 13
Let's first see if there is a way for x + y to equal 13, the greatest answer choice
Since we are told that x and y are each less than 6, there is no way for their sum to equal 13
Eliminate answer choice B
A) 11
Now let's try the second greatest answer choice, 11
Is there a way for x + y to equal 11?
You bet.
If x =5.9 and y = 5.1, then x + y = 11
Answer: A

x > y, x < 6, and y > -3, what is the largest prime number that could be equal to x + y?
x < 6
=> Largest value of x can be very close to 6
Lets say x = 5.9
Now x > y and y > -3
=> y can be maximum equal to 5.8999
To make x + y largest prime number we can start by making x + y integer
=> y = 5.1
=> x + y = 5.9 + 5.1 = 11
We cannot get a bigger integer value of x and y as x < 6 and x > y
So, Answer will be A
Hope it helps!
