Question

Маша и Таня купили одинаковое число почтовых наборов. Таня заплатила 90 рублей, а Маша на 5 рублей больше. Сколько стоит 1 набор и сколько наборов купила каждая девочка?

Answer 1

Таня заплатила 90 руб.
90 = 2 * 3 * 3 * 5
Маша заплатила 90 + 5 = 95 руб.
95 = 5 * 19
НОД (90 и 95) = 5 - наибольший общий делитель (цена набора)
90 : 5 = 18 почтовых наборов купила Таня
95 : 5 = 19 почтовых наборов купила Маша
Ответ: цена набора 5 рублей; Таня купила 18 наборов; Маша купила 19 наборов.

Answer 2

Calculation of the Cost and Number of Sets Purchased

To find the cost of one set and the number of sets purchased by each girl, let's analyze the given information.

- Tanya paid 90 rubles for her set. - Masha paid 5 rubles more than Tanya.

Let's assume the cost of one set is x rubles. Since Masha paid 5 rubles more than Tanya, Masha's payment can be expressed as x + 5 rubles.

To find the number of sets purchased by each girl, we need additional information. Unfortunately, the given question does not provide any information about the number of sets purchased by each girl.

Therefore, without the information about the number of sets purchased by each girl, we cannot determine the exact cost of one set or the number of sets purchased by each girl.

If you have any additional information or if there is anything else I can assist you with, please let me know!
