So. We have two dog breeds and bones. You`ll have the least trouble with the latter. Each bone represents one digit - a one.

You need to find the answer: the number that should be in place of the question mark in the fourth example. But first, you have to deal with the three previous ones, each separately.

Let`s start with the first one. Three Bulldogs add up to 15. They are completely identical. But that means each of them represents the same number. To find it, you need to divide fifteen by three.

In the second example, a Bulldog adds two dogs nicknamed Spotty. All these animals together make the number thirteen. As with the bulldog, each Dalmatian also represents the same number. To find it, you need to subtract the number corresponding to the first dog (which you already know) from thirteen. Then divide the result by two.

You already know the number that encrypts Spotty. But you can check yourself. If you add six to it, as there are exactly that many bones in the third example, and you get ten, then you know all your previous mathematical calculations were correct.
