The answer is A, because range of the set has to be equal or greater than difference between any two numbers in the set. As per (1), since difference between two numbers is > 5, so the range is also > 5. (2) does not give information about the value of k and the other numbers apart from k, So insufficient.

1. Sufficient
as we distance between two numbers in the set >5, Range will always be >5
2. Not sufficient
we know dont know anything about the values of these numbers . so not enough to comment about range.
Answer is A.

Is the range of the set of numbers {j, k, l, m,n, p} greater than 5?The range is the difference between the largest and the smallest numbers in the set. (1) k  n > 5. Since the difference between two of the numbers is greater than 5, then the range must also be greater than 5. Sufficient. (2) k is the greatest number in the set. Not sufficient. Answer: A.
