Is the prime number p equal to 3 ?
(1) p = n + 1, where n is a prime number. This statement implies that n and p are consecutive numbers and both are primes (also one is even and another odd). The only such pair is 2 and 3. Sufficient.
(2) p is divisible by 3. This statement directly says that p is 3 (which other prime can be divisible by 3?). Sufficient.
Thanks man, silly of me to ignore that point
