Is 1 < x < 2?


(1) 0 < x
(2) x < 3

Let's ask ourselves- what are the constraints on x?
- does it have to be an integer? No
- does it have to be +ve? Yes, the number is clearly between 1 and 2

Now let's analyse the statements:
S1. does x>0 necessarily mean that 1<x<2? Nope!! x can be 0.5 or 1.7 etc. We cannot conclude from this one. Insufficient. Strike off A and D.
S2. does x<3 necessarily mean that 1<x<2? Nope again! its can be 2.7 which is outside the range, or it can be 1.5 which is inside the range. Again, insufficient. Strike off B

Even after combining the two, we are left with the same questions as above.

the answer therefore is, E.
