## Sherlock Holmes GCSE Maths Challenge – episode 4 solution

Many congratulations to the **Episode 4** winners of our **Sherlock Holmes maths competition:**

**Jonathon Cox at The Littlehampton Academy**

for successfully working out where Holmes and Watson must go next.

**And the answer is:**

**OXFORD CIRCUS.**

We’ll be sending the winners a **FREE Class set of Longman’s unique AQA A-A* and G-F Practice Books (15 copies of each) ****and a tin of Cadbury’s Heroes.**

Coming up next… a spot of Christmas shopping in Episode 5 on Wednesday.

Here is the **winning solution to episode 4:**

The solution to how far away Moriarty is from the tunnel.

The path of the firework is y=300+44x-x^2. This is a quadratic so using the quadratic formula to find x when y=0

x= (-b +/- square root (b^2 – 4ac))/(2a)

where a=-1, b=44 and c=300

x = (-44 +/- square root (44^2 – 4X-1X300))/(2X-1)

x = (-44 +/- square root (1936 + 1200))/(-2)

x = (-44 +/- square root (3136))/(-2)

x = (-44 +/- 56)/(-2)

Either x = (-44 – 56)/(-2) = -100/-2 = +50 (where the tunnel is)

or x = (-44 + 56)/(-2) = 12/-2 = -6 (where Moriarty must have fired the firework from)

So 50 – -6 = 56 metres away from the tunnel

Moriarty is 56 metres awayThe Code.

Using the Coordinates of the Tate Modern (34, 14) and the code FG DG.

Using a shifted substitution D=1, E=2, F=3 etc

The Coordinates generated from substitution of CK EE gives (08, 22) which give the coordinates for Oxford Circus

Moriarty’s Target is Oxford Circus

## 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!

DON’T MISS OUT ON WHAT HAPPENS WHEN HOLMES AND WATSON ARRIVE AT THE LONDON EYE IN EPSIODE 2:
