title: How do i make random numbers (with limits) add a sum without using solver?
body: <p>I've been having trouble with my logic. I need a set of random numbers to add 100. The constraints applied to the numbers are as follow:</p>
  
  <p>number 1 - between 20 and 80</p>
  
  <p>number 2 - between 10 and 40</p>
  
  <p>number 3 - between 5 and 20</p>
  
  <p>I know it's probably simple, but can't wrap my head around it.</p>
  
  <p>Thanks in advance.</p>
