1. There are total of 100 prime numbers between 1 and p+1 The condition unambiguously says that p is 100th prime number. So, we can write out all 100 consecutive primes numbers and find p. sufficient.

2. There are total of p prime numbers between 1 and 3912. the same logic as in the fist condition. sufficient.

I even dare to say that p=3911. Why? Because I did not remember any DS, in which 2 conditions will be sufficient separately and lead to different values. _________________
