1) The distance between point A and point B is 25 2) Point A liest to the left of Point B. A. given that AC=5, BC=20 and AC=25 , C should be in between AB 2 alone is not suff

1) The distance between point A and point B is 25 2) Point A liest to the left of Point B. The answer is D  both statements are sufficient. (1) is sufficient for the reasons already stated in this post. (2) is sufficient because we know the relative placement of A and C and the distance between them. From the question stem, we know that point B can not be between A and C because of the large distance between B and C. Therefore, B can either be to the left of A (and thus, the left of C) or to the right of A (and thus, the right of C). Statememt (2) clears up this question.

Yeah the answer is D
from the stem we get 2 situations
1) A5C20B 2) B15A5C
now we need to find out which of the above 2 situations hold
choice A says A) Distance betn A and B is 25 which means situation (1) applies  sufficient Choice B says B)Point A lies left of point B  again situation (1) applies  Sufficient

aren't there 4 possibilities from the stem?? because both A could be 5 to the left or 5 to the right of C. and B could be 20 to the left or 20 to the right of C.
thus 4 possibilities:
1) BAC * 2) BCA 3) ACB * 4) CAB
therefore, given statement (1), possibilities 1 and 3 work. (1) is sufficient.
however, in possibilities 3 and 4, A lies to the left of B, yet only in 3 is C between A and B. (2) is insufficient.

C is the answer. Statement 1 and 2 each give 2 possibilities. Choice C gives one position of A, B, and C.
