Нехай камінчиків було $n$ штук. За умовою $30$ .

Перша умова: $n$ при діленні на 5 має дати остачу 1. Це можуть бути числа 31, 36, 41, 46.

Друга умова: $n$ при діленні на 3 має дати остачу 2. Це можуть бути числа 32, 35, 38, 41, 43, 45, 47, 49.

Єдине число, що задовольняє обидві умови, — це 41.

Відповідь: 41 камінчик.
