i think it C .. whats the OA
1. m-3z>0 .......... m >3z
m z m+z
4 1 5
-1 -5 -6
2. 4z - m >0 .............. m<4z
m z m+z
2 1 3
-5 -1 -6
after combining.... also does not give any result
3z<m<4z
m z m+z
3.5 1 4.5
So C.... pls. let me know the OA
1. m-3z>0 .......... m >3z

when we combine both equations ...add 1 and 2 we get z > 0 ...
No since z > 0 ...and from 1 we know that m > 3z m + z > 0 ..
Hence C ..
Hope this helps

IMO ans should be E
m + z > 0 ?
here we can say that if both m,n are +ve then m+z>0 & if boh m,n are -ve then m+z is less than 0
1) m-3z>0 or m>3z
here both are possible i.e m>3z>0 or 0>m>3z INSUFF
2) 4z-m>0 4z>m again both scenarios are possible here also INSUFF
Combine 3z<m<4z but still we can say that
3z<m<4z<0 & 0<3z<m<4z
INSUFF
E
m + z > 0 ?
here we can say that if both m,n are +ve then m+z>0 & if boh m,n are -ve then m+z is less than 0
1) m-3z>0 or m>3z
here both are possible i.e m>3z>0 or 0>m>3z INSUFF
2) 4z-m>0 4z>m again both scenarios are possible here also INSUFF
Combine 3z<m<4z but still we can say that
3z<m<4z<0 & 0<3z<m<4z
INSUFF
E

Thanks very much Sujay, did not sufficiently analyse this one
the scenario
3z<m<4z<0 cannot arise
Thanks for pointing out.
Happy New Year 2008! & best of luck for ur GMAT
