SUBMIT YOUR IDEABased on my understanding the count of type should be distinct because 3 people can buy meal associated with a ticket and if the ticket has three distinct type food and further if those are only Drink, Burger/Pizza and Side then thats the count.

@Community_Admin The exercise is a bit difficult to understand. It requests to run the calculations for "tickets since June 2013" (my understanding being 01.06.2013) whilst the solution is offered from tickets from 01.07.2013. I was checking my results and they were different, and after digging more into the solution I spotted the gap. It may be confusing for some, so maybe rephrasing it could help?
Thank you
My solution follows the text rather then provided output, as "since June 2013" in my world will start on 1st of June 2013 (Finance background, you need to be exact). I did test it on filter since 1st of July 2013, and it returned the same result as required task.
