All,

James weighs more than Kelly.
Luis weighs more than Mark.
Mark weighs less than Ned.
Kelly and Ned are exactly the same weight.

If the information above is true, which of the following must also be true?
(A) Luis weighs more than Ned.
(B) Luis weighs more than James.
(C) Kelly weighs less than Luis.
(D) James weighs more than Mark
(E) Kelly weighs less than Mark.

What's the best way to solve this reasoning?

J> K, L>M , M< N , K = N. This equation can be further deduced as J>K,N > M - > James weighs more than Mark.

IMO D

s1 J s2 K/N s3 N M ---> decreasing order

L can fill any of the three spaces,
1) ignore A,B,C
2) E is wrong

J (1st or 2nd) lot greater than last M
First take: 640 (50M, 27V) - RC needs 300% improvement
Second take: coming soon..
Regards,
HSPA.

IMO (D)

what have we got?

J>K.

L>M<N=K.


(A) Luis weighs more than Ned. - could be true (since both L and N > M. but relation between L and N is unknown.

(B) Luis weighs more than James - again replace K in the above logic. - could be true.

(C) Kelly weighs less than Luis. - could be true - refer logic of above.

(D) James weighs more than Mark J>K=N>M. Therefore, J>M - must be true!

(E) Kelly weighs less than Mark - false.

First of all, this is definitely NOT a GMAT question.

Second of all, the correct answer is most definitely choice A, not (D).

From the information in the passage, we can infer the following:

(I) L...M...(K=N)
(II) J...(K=N)

From (I), we can see that (A) must be true. However, we don't know how J relates to L or M. L...M, but J can intervene any where (before L, in between L and M or afer M).

Can you post the source?

This topic does not warrant much discussion.This question must belong to the old gmat paper tests that were phased out to usher in the online Gmat version.It was a long time back and such questions no longer feature on the gmat.

This expert's answer is definitely not correct.

We are given: J>K, K=N, and M<N
THEREFORE J>K,N>M
James weighs more than Mark is definitely given through the data available.
