Statement 1 says . x is > 30 .
=> x is 31
Sufficient

Statement 2 says , tens digit is greater than units digit .
=> x is 31

From the question stem x can be either 13 or 31.

1) x is greater than 30. So x is 31. SUFFICIENT
2) The tens digit of x is greater than the units digit of x. This is possible only when x is 31. SUFFICIENT.

OPTION: D
