I was able to solve this using the wavy line method, and it was easy, as one of the statements was sufficient.
But I wonder, if we had to solve both statements together, how would the wavy line work in a case like that, for a question like this (Assuming none of the statements was sufficient on its own).
KarishmaBYou will use wavy line on each statement independently and get the set of values for each.
So say statement 1 gave you 1 < x < 4
and statement 2 gave you 2 < x < 5
Neither stmnt alone is sufficient.
Using both together, you get that both conditions should be met. So x should be between 2 and 4 (since it must be greater than 1 and 2 and less than 4 and 5 so it must be greater than 2 and less than 4).
Then we know that x is 3.
If both conditions together do not give a unique value for x, answer would be (E)
