For numbers divisible by 3, b is always implied by a. So b does not bring any new information.

For Staement 1 , We can have three two didgit Numbers : 12 , 21, and 30  Not Sufficient
For Statement 2 , We can have any Number from 12 (Since Required Condition Says Two DIGIT) Upwards , adding 3 to each Number. (Multples of 3 Above 12)
Combine Both , We can norrow down the choices to three Numbers  12 , 21 & 30, then again We need ONE Answer but We have three.
So the Ans is E .

Ans e We have 3 options: 12,21,30 1. All options are divisible by 3. We cannot be sure. Insufficient. 2. x is divisible by 3: This we can infer from statement 1 only. No real need for this statement. Anyways, all 3 options are divisible by 3. Insufficient. 1 & 2 also are insufficient as they do not give any other information about the numbers so that we can differentiate between them. answer E.

OA: E Quote: What is the value of the 2digits integer x?
a) The sum of the digits is 3.
b) x is divisible by 3. OA: E a) The sum of the digits is 3. x can be 12,21,30. As There is no unique value of x, Statement 1 alone is insufficient. b) x is divisible by 3. x can be 12,15,18,21,24,27,30 .......... and so on. Combining 1 and 2, x can be 12,21 and 30. combining 1 and 2 is also insufficient.
