@Aditi: The ropes burn at non-uniform rates. So for your solution, you would have to fold it in half according to time, not according to length. But you don't know where the half-hour point is unless you light one end of the second rope at the same time you light both ends of the first rope. When the first rope burns out, you will know where the half-hour point is on the second rope.
