|----|------------------|
A C B
|- 5--|
|--------20-------|
|-----------25----------|

Only way statement 1 works is above. Statement 1 is sufficient.

Statement 2 is a trap. If you do statement 1 first, you may be fooled into thinking, because A is to the left of point B that it is the same as above. However, it could also be:
|----|------------|
C A B
|-5--|
|---20-------|
|-------20--------|

Doh, it didn't preserve the white space. Anyways, in Statement 2 we don't know the distance between A and B, therefore it could 20 or 25 units apart. C could be to the left of A or in the middle.

statement 1 is clearly sufficient.
from 2 A lies left of B so C should between A & C
what's wrong with this?

a) the distance between A & B is 25
b) point A lies left to pont B

For statement 2 following cases are possible:
A--(5)--C-------(20)-----------B
C--(5)--A-------(15)---------B

So this statement is not sufficient.
