Is m+z >0
1) m-3z>0
2)4z-m>0
1) m>3z - INSUFF cant say much about m or z
2) 4z>m - INSUFF can say much about m or z
combining the two
3z>m>4z, so z has to be positive because 3z<4z. and since z is positive, m also has to be positive.
Hence C.
Is the way I have solved right? Is there any other approach to this problem
