If a, b, c are three numbers on the number line shown above , is c between a and b.

(1) b <0 (2) a-b>c

For (1) and (2): From (2), we know that 0>a-b>c and from (1) that b<0. Place a,b and a-b on the number line (see the attached drawing). You can see that c can be between a and a-b (which means that c is between a and b) or on the left of a (meaning c is not between and b). Not sufficient.

Answer E.

Hi Gurpreet, in your screenshot I dont see the line segment where points 'A' and 'B' are marked like in the original question. In the original question the line segment is given with the points positioned in it. So that makes a difference. These questions are similar, not identical.

I have not posted the real question. I have just posted the explanation. And the question is exactly same. _________________

I have a question here if I may

Should we assume that a,b are given in order, that is as shown in the number line? I understood that one should trust the order of points shown either on number lines or graphs according to GMAT

Please confirm Thanks! Cheers J

Yes, from the diagram we can derive that a<b. _________________
