please help

Answer: (D). Both the statements are alone sufficient.

Solution:

Check the attached image.


On the number line there are only two conditions where B can lie, marked as B and B'.

As first statement state: distance between A and B is 25 => B' not possible as distance between A and B' is only 15 which contradicts 1st statement. => C lies between A and B.

Statement 2 state, Point A lies left to B => C lies between A and B.

Image is self explanatory, as B' is not possible at all with any one of the mentioned statement

I agree that statement (1) is sufficient.

However, for statement (2), why couldn't it go:

C----5------A-------------15--------------B

to get a "no" answer?

In fact, since we don't have any directional info other than statement (2), how can it possibly matter if A is to the left of or to the right of B? Even in your sketch for statement (1) it could have gone:

B----------20------------C----5----A

or

A-----5----C------------20---------B

(1) is sufficient, but (2) isn't: choose (b).

thanks a lot guys...

Yeah you are correct Stuart. My bad, I missed that point.
