3.2@#6

IF @ and # each represent single digits in the decimal above,what digit does @ represent??
1. when the decimal is rounded to the nearest tenth,3.2 is the result.
2. when the decimal is rounded to the nearest hundreth,3.24 is the result.

Statement 1.
since 3.2 is the answer...
@<5
which can be 0,1,2,3 or 4
insufficient

Statement 2
rounding to the nearest hundreth 3.24 is the result...
So when @ is 3, # may be 5,6,7,8 or 9
or when @ is 4, # may be 1,2,3 or 4
So @ may be 3, 4....
insufficient

using both also we get @ may be 3 or 4
So insufficient...
Hence answer is E
