Show/Hide Answer and Explanation
Correct Answer: E
Arithmetic operations: If the units digit of nis greater than 2, then it can only be the digits 3, 4, 5, 6, 7, 8, or 9.
Since (1) and (2) together yield the same information but with no direction as to which to choose, there is not enough information to determine the answer.
The correct answer is E; both statements together are still not sufficient.
