Допустим, в обычное время перелет из Санкт-Петербурга в Ереван стоил 10, но Константин прилетел за 320.

С другой стороны, рестораны, на которые он в Питере тратил 20 тысяч рублей в месяц, здесь стоят ровно в четыре раза меньше.

Вопрос: за какое время он выйдет в ноль, то есть окупит свой билет?

Посчитаем для начала, какая была переплата за билет: 320 минус 10 будет 310 тысяч.

С другой стороны, рестораны вместо 20 тысяч он будет тратить 5000 в месяц.

Но если он тратит 5000, значит, экономит он 15.

Тогда не сложно посчитать, что за 20 месяцев он сэкономит 300 тысяч.

Соответственно, за 21 месяц он выйдет в плюс.

21 месяц — чуть меньше двух лет.

Другой вопрос, что, конечно, здесь не в четыре раза меньше, поэтому это небольшая.
