Consider the image.
B is a point equidistant from points A and C. How far is B from either point ?
(1) The coordinates of the points A and C are (1,2) and (2,1) ,respectively
Not sufficient, as shown.
(2) The distance between A and C is √2
Clearly not sufficient.
(1+2)No new info, and point B could still be anywhere on the line shown.
you are really a stunning math killer.....
i knew the concept but just wanted to be sure about it, you know its DS problem... so thanks again brother...... you deserve two kudos for this diagram......
