Chocolate Tin Maths

There are several different chocolate tins available to buy around Christmas time, but which is best for you and your family?

This is not just about which flavours different family members like but the amount of them within the mix.

You would hope that in one of these tins, you would have the same number of each flavour.

Unfortunately, this is not true.

Below are some pie charts showing averages for how many of each flavour are in each of the four top selling tins.

Today's Challenge

Siân managed to get a great deal on a 2.4kg refill box of Celebrations. She wanted to know if the same percentages applied with a larger box.

Below is a comparison between the tin and her box.

A repeat of the above pie chart for a tin of Celebrations

A pie chart for Siân's 2.4kg box of Celebrations. It is made up of; 12% Maltesers, 14% Bounty, 16% Milky Way, 8% Twix, 19% Mars, 15% Snickers, 8% Galaxy, 8% Galaxy Caramel.

A tin of celebrations holds 60 chocolates, and the box Siân bought contains 4 full tin refills.

How many more Mars would she get in the box compared to if she bought 4 tins?

How many Twix will she miss out on if she buys a box instead of 4 tins?

Her family's favourites are Milky Way, Bounty, and Snickers. Which is the best option to buy for them (the box or 4 tins)? How many more would they have in the better option?
