Could someone explain why statement 1 ALONE is not sufficient to answer the question? I think it is. P= 1 or 4. So (3+2p)/3p= 5/3 or 11/12.
Although there are two answers, they are all the value of (3+2p)/3p.

2 solutions are insufficient on data sufficiency questions since we do not "know" the solution

Xiao Meng, I think they are looking for just one answer. I admit this practice question is not very well worded.

Xiao Meng, I think this question is not right. In the real GMAT, the solutions of the two statements won't contradict each other. I will contact the author and let him know.

This would never be on the GMAT. DS answers cannot contradict each other.

Tristan Loiselle and others, you are right that answers in DS cannot contradict each other, as we have mentioned.
We just got the correction from the publisher:
What is the value of (3 + 2p) / 3p?
(1) p^2 - 5p + 4 =0
(2) The value of 1/p + 2/3 is 5/3
