Question:
What is the value of x?
Statement 1 : x/3 = 5/3
Statement 2 : x2-8x+16=0
My solution :
Statement 1 leads to the unique answer x=5.
Hence B,C,E are ruled out.
Statement 2 leads to another 'unique' answer x=4.
How do we handle this case where Statement(1) and Statement(2) lead to different answer choices, albeit each answer is unique?
Kindly help.
Thank you,

It will never happen in an official question or a reliable source. If you encounter such question, look at the source and then never look at that source for the rest of the preparation, because you have to go for quality and quantity.
However, technically speaking, since each statement is sufficient, the answer is D, but as I said the question is faulty.

On the GMAT, two data sufficiency statements always provide TRUE information and these statements never contradict each other.
So, for example, we can not have answer 2 from statement (1) and answer 4 from statement (2), as in this case statements would contradict each other.
Or for example in YES/NO DS questions we cannot have answer YES from statement (1) and answer NO from statement (2), as in this case statements also would contradict each other.
