On the number line, the distance between point A and point C [#permalink]  20 Oct 2006, 00:54
On the number line, the distance between point A and point C is 5 and the distance between point B and point C is 20. Does point C lie between point A and point B?

(1) The distance between point A and point B is 25

(2) Point A lies to the left of point B

OA is A. But i think (2) is also sufficient on its own. If point A is to the left of point B, then C has to be in between bec of the given distances in the question stem. Can anyone explain why (2) is not sufficient?

In (2) A could lie both to the left of B & C (AB then = 25) and to the right of C and to the left of B (AB then = 15)

therefore (2) is not suff

Exactly. Try drawing a number line as per helg's comments and you will see this should be A.
