I'm trying to find some online questions and training material related to this sort of question. It's not something that I can identify the name of:
A raffle has these prizes (ending 00 @ £12, ending 5 at £1.5), and tickets cost 50p. If all the winning tickets from 750 are sold (and some non-winning tickets), the total profit is £650. How many non-winning tickets were sold?
The solution goes along the lines of
- calculate total winning tickets
- calculate total prize money from #tickets
- calculate total revenue
- calculate total # tickets
- subtract willing tickets
- final answer.
I understand how to solve this specific problem, but is it a standard type of question, or just a one-off type of question? I'm hoping that there is a simple strategy for explaining this sort of question.
