Hi,
I thought the answer is B) but correct answer is E). Please explain
Are the numbers k/4,z/3 and r/2 in increasing order?
(1) 3 < z < 4
(2) r < z < k
My logic is.....
k/4<z/3<r/2
or after multiplying by 12 ---> 3k < 4z < 6r and we have r<z<k
pick numbers
r=1, z=2, k=3 so we have 9 < 8 < 6 not true
pick numbers
r=1, z=8, k=12 so we have 36 < 32 < 6 not true
pick numbers
r=-1, z=0, k=12 so we have 36 < 0 < -6 not true
So we know that this is never true
Please let me know whats wrong with my logic here
