(1) Possible values are 225,441, etc.
Thus, insufficient.

(2) Again, the possible values are 225,441, etc.
Thus, insufficient.

(1) and (2) together, the possible values are 225,441, etc.
Thus, insufficient.

Therefore, the correct answer is option E.

So number is AAB. Can it be 11B--No, it is between 100 and 121..22B.. Yes it can be \(15^2=225\)... Next would be \(21^2=441\)

2. X is an odd number
Insuff

Combined..
It can be 225 or 441

E
