**Concept: The question tests on the ****reasoning**** ****associated**** with Range of a set of inputs.**

**Solution:**

St(1)- S has 7 numbers but we have no information of T and we cannot determine if x is greater than y**.(Insufficient)**

St(2) T has 6 numbers but we have no information of S and we cannot determine if x is greater than y. **(Insufficient)**

__Using both (1) and (2)__

Let set T = {1,2, 3,4,5,6}

Then **y = Range of set T** = Max-Min value in the set

=6 – 1 = 5

Let set S = {1,2,3,4,5,6,7}

**x = Range of set S **

= 7 – 1 = 6

So, x>y **(ANSWER TO QUESTION IS YES)**

Now let’s take set T = {1,2,3,4,5,6} and we have y = Range of set T = 6 – 1 = 5

Let set S = {1,2,3,4,5,6,6} and we have x = range of set S = 6 – 1 = 5

Here x = y. **(ANSWER TO QUESTION IS NO)**

Thus using both too, we are unable to answer the question and hence option (E)
