K/4 < Z/3 < R/2 ??

statement 1: insufficient
No info on k or r

statement 2: insufficient
If R=3, Z=4, and K=5, we get 1.20 < 1.25 < 1.50, increasing order
If R=-5, Z=-4, and K=-3, we get -3/4 < -4/3 < -5/2, not increasing order

statements 1+2: insufficient
If r=2, z=3.5, and k=10, we get 2.5 < 7/6 < 1, not increasing order
If r=3, z=3.5, k=4, we get 1<7/6<1.5, increasing order

Answer E!
