## Sherlock Holmes Episode 1 solution…

Our thanks to everyone who’s taken part in **Episode 1** of our Sherlock Holmes competition: **The Mystery of the Devil’s Eye!**

In **Episode 1**, Holmes and Watson are called to Harrods by a frantic Inspector Lestrade: the world’s largest Ruby, the Devil’s Eye, has been stolen and he doesn’t know where to go next. There are just a few cryptic clues that only a master of deduction, *and mathematics,* could solve…

**AND THE ANSWER IS…**

**THE LONDON EYE! **

Our congratulations to this week’s winners: **CLASS 10 Set 3 from Sutton Grammar School in Surrey.**

Here’s their answer:

If you work out the volume of the ruby; (area of rectangle + area of trapezium) x length

((10 x 3.5) + (7 x 2.5)) x 11 = 577.5 cubic cm.

The Mass is density x volume; so 4 x 577.5 = 2310 g

If we split the answer 2310 in to 2 parts we got the co-ordinate (23, 10)

This is THE LONDON EYE

{and the thief keeps talking about eyes at the start of the note}

[We also worked out the thief got through Door B; if you draw the lasers as lines on the graph, all the doors are blocked except B]

We’ll be sending the winners a **Sherlock Holmes DVD** and a **tin of Cadbury’s Heroes** in the post!

## AQA Functional Maths teacher resources: FREE samples available to download

Back in the depths of August, we published the teacher resources for our** AQA Functional Maths 2010 series**: a **Teacher Guide** and an **ActiveTeach DVD-Rom**. Both resources cover Levels 1 & 2.
