Statement 1 is sufficient.
as v+z =6, both v and z have to be 3.

thus r=3.

b) when r=8, we will have 1.08^2 = 1.1664.

a) we can find r.. sufficient

Hey,
I always try to simplify equation a bit with algebra and try to put numbers. Specially in cases such as mean and median...
But if question is like a>b is given, find if b>c or not, I try to pick numbers..
Dunno if this is of much help but always go with your intuition
