If 3 < x < 6 < y < 10, then what is the greatest possible positive integer difference of x and y?
A. 3
B. 4
C. 5
D. 6
E. 7
x>3 & y<10
Let's say x = 3.01 & y = 9.99
y - x = 6.98
So greatest possible positive integer = 6
IMO D
If we read this question literally, the parameters indicate the difference must be an integer.
Since 6.98 is the difference, and is not an integer, we cannot use this.
9-4 = 5. 5 is the difference, and is an integer, so we can use this.
It frankly depends on how one defines "integer difference". I define by literal meaning, the difference must be an integer.
Edit: I see we can get 6 through taking the difference of non-integers within the stated perameters. but even then, how do we define "integer difference"? The difference of integers in the range?
Therefore, again, I see this question stem as lacking clarity on the required operation.
