Mom brought 10 snacks of three types: there were fewer coconut snacks than lollipops, and the most were caramel chews. Josef chose two different types of snacks, Jakub did the same, and for Jan, only snacks of the same type were left.

How many coconut snacks, lollipops, and caramel chews did Mom bring?

Hint. Which type of snack was left for Jan?
When Jan received $\mathrm{k}$ snacks, there were 6 of the same kind, and they were caramel chews - if they were coconuts or laskonky, there would have to be more than 6 chews and more than 10 snacks in total. Therefore, there were at least 6 caramel chews originally, and mom brought

- either 1 coconut, 3 laskonky, and 6 chews,
- or 1 coconut, 2 laskonky, and 7 chews.

The first option is not suitable - for Josef and Jakub to each have two different kinds of snacks, at least one of them would have to choose a chew as well, and then there wouldn't be 6 left for Jan.

The second option is suitable - one of the first two boys chose a coconut and a laskonka, the other chose a laskonka and a chew, leaving 6 chews for Jan.

Mom brought 1 coconut, 2 laskonky, and 7 caramel chews.
