Maths Week: Tuesday's puzzle of the day
We’re setting you a little brainteaser each day this week to highlight a drive to improve the country’s numeracy skills.

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

Each morning this week, we’ll be 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.

Tuesday’s puzzle:

Some predict that the VAT rate for restaurants will be put up from 9% to 13.5% later today. If you pay €100 for a meal out at present, what would you pay for the same meal in January at 13.5% VAT?

Poll Results:

C. €104.50 (1778)
B. €104.13 (1690)
D. €113.50 (1337)
A. €96 (11)

All answers will be revealed on Friday afternoon. You’ll see what other readers are thinking when you make your choice above and the pie chart shows the most popular option. (We’re not saying that the most popular will be the right one!)
