Hi , I just got a doubt while working on a problem in gmat practice.. the product of 2 prime numbers us btwn 59 and 109. One of the prime is between 5 and 12 and other between 11 and 21. What will b the sum of these 2 prime numbers a) 18 b) 19 c) 20 d) 24 e) 26.

In this sum does it mean that we can include 5 as it says between 5 and 12?
