:cry: I cant solve these types of questions involving algebra even after lotsss of practice
If p is a prime number greater than 2, what is the value of p?
(1) there are a total of 100 prime nos between 1 and p+1.
(2) There are a total of p prime nos between 1 and 3912.
There is nothing to solve, the question is testing your reasoning skill.
statement 1: tells you that p is the 100th prime number, (FYI, the value of the 100th prime number is 541, but you don't need to know that)
statement 2: says that if there is (for example) 23 prime numbers between 1 and 3912, then p is 23. If you look up the prime number table, there are probally 541 prime numbers between 1 and 3912.
