T!=R
R!=T=(T!)!=>T=1=>R=1 or T=2=>R=2

So how are we supposed to answer this question? C or E

There are two solutions: R=1;T=1 or R=2;T=2

If we are asked for the value of T and R then the answer is E since we don't have one and only one value for T and R.

If we are asked for the possible numbers of T and R then the answer is C.

Is this correct? Or I'm just complicating things too much and answer is always C?

In DS questions, it is required to find a unique solution.

Here we have two possible solutions.

So, IMHO, the answer is E.

If there are two possible values, even when they are combined, then the answer must be E.

after combining the two sets, we have two pairs: (1, 1) and (2, 2)
Agree, it is E.
