Explain what does the statement 2 mean?
R = P/Q gives us a hint about how to find out if P = R. R will be equal to P only when Q is 1, so this is what we need to find out.
1. P > 50 tells us nothing about Q, so 1 is insufficient.
2. I believe that you meant "0 < Q < 20" - in this case, 1 is in the interval, but we can't say if Q is 1 or any other number between 0 and 20. Again, 2 will be insufficient.
However, if you did mean that Q = 20, then 2 will be sufficient, since it's enough to prove that R is not equal to P.
