I think ans should be option A. Because statement 1 is enough to give distance between A and B ( which is equal to x=4 KM), but can not be given by statement 2, which says any integral distance greater than or equal to 10 Km.

**The question is followed by two statements I and II.**

**Mark **

- if the question can be answered by any one of the statements alone, but cannot be answered by using the other statement alone.
- if the question can be answered by using either statement alone.
- if the question can be answered by using both the statements together, but cannot be answered by using either statement alone.
- if the question cannot be answered even by using both the statements together.

What is the distance x between two cities A and B in integral number of kilometres?

- x satisfies the equation $\log_2 x = \sqrt{x}$
- $x \geq 10$ km
