If N is a natural number less than 100, then for how many values of N are the numbers 6N+1 and 15N+2 relatively prime?

• N cant be an even number. So,N must be an odd natural number.
  when N=1,3 6n+1 and 15n+2 are primes.
  when N=7 15n+2 is not a prime number.

• N=26(no of prime numbers below 100 )
  but 2 is a prime no doesn't satisfied THE EQUATIONS
  1 is satisfied
  so total no values is
  N= 26(1,3,5,7,11,13,17,19...................97).
