1. Each of the examples below are such that the tens digit of r (equal to 4 in both examples) is greater than each of the three digits of t.
Example I: r = 242 and t = 222. Example II: r = 242 and t = 333.
Note that r is greater than t in Example I and r is not greater than t in Example II; NOT
sufficient.
2. Given that the tens digit of r is less than either of the other two digits of r, there is no information about the three-digit integer t ; NOT sufficient.
Taking (1) and (2) together, the hundreds digit of r is greater than the tens digit of r by (2) and the tens digit of r is greater than the hundreds digit of t by (1). Therefore, the hundreds digit of r is greater than the hundreds digit of t and it follows that r is greater than t.
The correct answer is C;
both statements together are sufficient.
