+# cakes-swerc-2020-2021
+
+Created by [@Divlo](https://github.com/Divlo) on 23 April 2022.
+
+## Instructions
+
+This summer, you plan to organize a large party and invite many
+friends. They have a sweet tooth, so you plan to bake nice cakes for them.
+You know the recipe for a nice chocolate cake, and you want to cook as
+many of them as possible.
+
+Given the `N` ingredients needed to make a single cake and the
+ingredients that you have in your kitchen, how many cakes can you
+make?
+
+### Input
+
+- **Line 1:** Single integer `N` for the number of ingredients
+- **`n` next lines:**, One for each ingredient. Each of these lines contains two positive integers:
+the first one is the required quantity of this ingredient per cake, the second one is the quantity of
+this ingredient you have in your kitchen.
+
+### Output
+
+The output should contain a single integer: the maximum number of cakes you can make using the
+available ingredients.
+
+### Limits
+
+- 1 <= `N` <= 10
+- All ingredient quantities will be integers between 1 and 10 000
