10. Is mn < m/n

(1) mn is a positive integer.

(2) n is a negative number.

My aplogies guys.

Lets see all possible scenarios,

Stement 1. mn is positive, could mean m = 4, n =2 or vice versa, and mn>m/n. However lets assume m = 4 and n =1/2 mn =2, and m/n could be 8. In this case mn<m/n.

So statement 1 is insufficient
Statement 2 say tht n is a negative integer, this standing alone does not help us in any way as n=-4 and m = -2 and mn=8 while m/n could be 2 or i/2, in which case mn>m/n. however if m =-4 and n=-1/2, then mn<m/n, Statement 2 is thus insufficent.

When you combine the two, it still does not help, this is the case i showed in 2, because combining the two would mean that m is also negative.

Thus E is the likely answer
