ENGAGE THOSE BRAINS, folks: we have a teasing question for you.

Each morning this week, we have been setting you a (not too) tough riddle to get the cogs whirring and test your mathematical mettle.

If this prospect fills you with either a. joy, or b. dread, the site is worth a look – with events for maths fans and for those who might feel the need to brush up on their numeracy skills. The events are running from now until Sunday.

Friday’s puzzle:

A large tea is €1.20, a medium tea is €1, while a small is 60c. I buy 10 teas for €10, how many teas and of what size do I get?

The answers to each of this week’s puzzles will be revealed this afternoon at 2pm on
