The number of employees in Obelix Menhir Co. is a prime number and is less than 300. The ratio of the number of employees who are graduates and above, to that of employees who are not, can possibly be:

1) 101:88
2) 87:100
3) 110:111
4) 85:98
5) 97:84

• 5) 97:84
  since number of employees is a prime num, so the sum of numerator and denominator should be a prime num.
  
  101+88=189 (not prime)
  87+100=187 (not prime)
  110+111=221 (not prime)
  85+98=183 (not prime)
  97+84=181 (prime), and hence the answer.
