Question

Помогите плз записать решение задачи. Оля старше Светы на 4 дня и не младше юли.юля старше кати на 9 дней. Маша старше Оли на 7 дней. Старше юли только один человек. Младше Светы только один человек. На сколько дней самая старшая из девочек старше самой младшей?

Answer 1

Ответ: 9-7=2 маша самая старшая а Катя самар младшая тоест мы берем и получается 9-7=2

Answer 2

Старше Юли только один человек

Младше Светы только один человек

Это значит, что в по убыванию возраста Юля будет стоять 2ая, а Света 4ая

Далее найдём ту, что старше Юли, их получается две, вусловии сказано, что одна, но в тоже время Оля не младше Юли это значит, что они могли родиться в один день.

Юля = Оля

Получаем, что Маша первая, Оля и Юля вторые, а Света становится третьей .

Остаётся одно место и одно имя - Катя самая младшая.

Маша старше Оли на 7 дней, Оля и Юля ровесницы, Юля старше Кати на 9 дней.

7 + 9= 16 дн

Примечание: Число 4 (Оля старше Светы на 4 дня) это промежуточное число, роли не играющее, только при установки возрастов.

Problem Analysis

To solve this problem, we need to determine the age difference between the oldest and youngest girls based on the given information. Let's analyze the information provided:

- Olga is older than Svetlana by 4 days and not younger than Yulia. - Yulia is older than Katerina by 9 days. - Masha is older than Olga by 7 days. - Only one person is older than Yulia. - Only one person is younger than Svetlana.

We need to find the age difference between the oldest and youngest girls.

Solution

Let's break down the information and solve the problem step by step:

1. Olga is older than Svetlana by 4 days and not younger than Yulia. 2. Yulia is older than Katerina by 9 days. 3. Masha is older than Olga by 7 days. 4. Only one person is older than Yulia. 5. Only one person is younger than Svetlana.

Based on the given information, we can make the following deductions:

- Since Olga is older than Svetlana by 4 days and not younger than Yulia, we can conclude that Olga is older than Yulia by at least 4 days. - Since Yulia is older than Katerina by 9 days, and only one person is older than Yulia, we can conclude that Yulia is the oldest girl. - Since only one person is younger than Svetlana, and Olga is older than Svetlana, we can conclude that Olga is the youngest girl.

Now, let's calculate the age difference between the oldest and youngest girls:

- Yulia is the oldest girl. - Olga is the youngest girl.

To find the age difference, we need to subtract Olga's age from Yulia's age.

Let's assume Yulia's age is Y and Olga's age is O.

From the given information, we know that: - Y - O = 4 (Olga is older than Svetlana by 4 days) - Y - O >= 4 (Olga is not younger than Yulia)

Since Yulia is the oldest girl, we can assume her age to be the maximum possible value. Let's assume Y = 365 (1 year).

Substituting the values, we have: 365 - O = 4 O = 365 - 4 O = 361

So, Olga's age is 361 days.

The age difference between the oldest (Yulia) and youngest (Olga) girls is: Y - O = 365 - 361 = 4 days.

Therefore, the age difference between the oldest and youngest girls is 4 days.

Conclusion

Based on the given information, the age difference between the oldest and youngest girls is 4 days. The oldest girl is Yulia, and the youngest girl is Olga.
