Is |A - B | > | A - C | ?

1) | B | > | C |
2) A > 0

The method other than picking the number:

imagine FOUR points A, B, C and O on the number line. O corresponds to 0 on the number line

Now the question is |A - B | > | A - C | which is basically asking: is the segment AB > segment AC on the number line?

Statement 1 : Segment BO > segment CO, In other words, B is farther than C from 0. B and C could be on either side of 0. But the absolute distance of B from 0 is greater than the absolute distance of C from 0. we do not know the position of A. So not suffeciaent.

Statement 2: it is self explanatory. In our number line, this does not help us identify the position of point B and C. NOT SUFFECIENT

Both together: If you combine the above two explanation, you will realize that it is not suffecient.

hi gmatblast,

Have u ever taught kids? This is one of the best explanation I have come across. I will definitely apply this in Quant.

Well I am glad you liked the explanation. And as for teaching kids, nop I have never taught to any kids... now as you have mentioned, I should probably think about it in future.

By the way, I got the concept of distance for absolute value from the following link. You are probably already aware of it. But just in case
