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 .

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.

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.

What is the value of the two-digit integer x ?

Let 2-digit number be ab.

(1) The sum of the two digits is 3.
a+b=3
(a,b) = {(3,0),(1,2),(2,1)}
NOT SUFFICIENT

(2) x is divisible by 3.
10a+b=3k
(a,b) = {(3,0),(1,2),(2,1)}
NOT SUFFICIENT

(1)+(2)
(1) The sum of the two digits is 3.
a+b=3
(2) x is divisible by 3.
10a+b=3k
(a,b) = {(3,0),(1,2),(2,1)}
NOT SUFFICIENT

IMO E
