The Cookie Jar:

Maria baked a batch of cookies. She noticed something interesting about the number of cookies she made:

  • The total number of cookies is greater than 20 but less than 30.
  • The number of cookies can be divided equally into groups of 5 with no cookies left over.
  • If you were to try and divide the number of cookies equally into groups where the number of groups is a prime number (like 2, 3, 5, 7), you would only be able to do this perfectly for one of those prime numbers.

How many cookies did Maria bake?

Conclusion: The number 25 fits all the conditions. It's between 20 and 30, divisible by 5, and can only be divided equally into groups where the number of groups is a prime number (specifically 5).
