If zt<-3, is z<4?

1) z<9
2) t<-4

1) we know z must be <9, but it does not state if it is <4; so n.s.
2) z(-4)<-3
z>12 - so we know that z is not <4; hence B is suff...

Is the reasoning correct?

I think the answers is E to this problem.


Stmt I)

z<9
zt<-3

z=8 t =-5/8 z<4 is false

z= 3 t=-2 z<4 true


INSUFF

Stmt II

z=7 t=-5 z<4 false
z=3 t = -5 z<4 true


INSUFF

Combined they stil will be INSUFF

E)

Your reasoning for 1) is correct but for 2) is wrong.
its given t < -4, so u cant plug t = -4 and ans the question.
also, lets say t = -5, then z(-5) < -3 or z > 3/5. It will not be 15. I hope you understand my point.

If zt<-3, is z<4?
1) z<9
2) t<-4

Main statement:
zt<-3. Divide both sides by t
t>0 then z<-3/t
t<0 then z>-3/t

(1)
z<9
INSUFF

(2)
t<-4
t<0 then z>3/4,
INSUFF

(1)(2)
3/4 < z <9
still INSUFF

E

what if Z=1 and t=-5

zt = -5 < -3

what if Z = 5 and t = -5

zt = -25 < -3

so Z can be less than or greater than 4

Hence, E
