M,N,P are positives we need the largest number.
Lets dive into the statements then =.
Statement 1 =>
MN>NP
As N>0
hence we can divide both sides of the inequality by N without altering the sign.
Hence M>P
But what about N?
Not sufficient.
Statement 2=>MP>MN
As M>0
hence we can divide both sides of the inequality by M without altering the sign.
Hence P>N
what about P?
Not sufficient.
Combing them we can say that
M>P
P>N
the ordering of the numbers is =>N,P,M
hence M is the largest.
Hence C

Of positive integers m, n, and p, which is the greatest?
(1) mn > np
(2) mp > mn
FROM STATEMENT - I (INSUFFICIENT )(1) mn > np
(2) mp > mn
mn > np
Or, m > p
FROM STATEMENT - II (INSUFFICIENT )
mp > np
Or, m > n
FROM STATEMENT - I & II ( SUFFICIENT )
m > p & n
Hence, BOTH statements (1) and (2) TOGETHER are sufficient to answer the question asked, but NEITHER statement ALONE is sufficient to answer the question asked, answer will be (C)
