A brainteaser was placed on our Facebook page this morning. How did you get on?

If you've come here looking for the answer, then look no further...

This weeks brainteaser asked you to solve the following:

Peter is 20 years old, Raymond is 25, Veronica is 18 and Julian is 12.

How old is Yvonne and why?

Any ideas?

scroll down for the answer

The letters in each person's name have numerical values A-Z=1-26.

The third letter of each name is equal to each person's age so Yvonne is 15.

You can play along on Facebook, Twitter and Instagram every Tuesday with a new teaser each week!
