3p+4q=11. What is q?
Statement 1. p is prime. so p can be 2, 3, 5, 7, 11, ...
with every new value of p, there will be a new value of q. Infinite values possible. Insufficient
Statement 2. q=-2p Or p=-q/2
We can substitute this in original equation. 3(-q/2) + 4q = 11
5q/2 = 11 or q=22/5. Sufficient
Hence B answer
