Question

Лиса Алиса и кот Базилио перевоспитались и занялись благотворительностью в первый раз Алиса пожертвовала приюту для бездомных животных на 25% золотых монет меньше, чем Кот Базилио, а во второй – на 20% больше. В общей сложности Алиса пожертвовала на 10% больше Базилио. Наименьшее количество золотых монет, которое Алиса и Базилио пожертвовали приюту бездомных животныха.55б.189в.110

Answer 1

В общей сложности приюту для бездомных животных Кот Базилио пожертвовал х монет, а Лиса Алиса х + 0,1х = 1,1х (на 10% больше). Всего было пожертвовано х + 1,1х = 2,1х.
2,1х = 189
х = 189 : 2,1
х = 90 (монет) - пожертвовал Кот Базилио
90 + 0,1 * 90 = 99 (монет) - пожертвовала Лиса Алиса
Ответ: б. 189 - наименьшее количество золотых монет.  

55 = 5 * 11
110 = 2 * 5 * 11
189 = 3 * 3 * 3 * 7
21 = 3 * 7
НОК (21 и 189) = 3 * 3 * 3 * 7 = 189

Problem Analysis

We are given that Alice and Cat Basilio engaged in charity work. In the first instance, Alice donated 25% fewer gold coins to an animal shelter than Cat Basilio did. In the second instance, Alice donated 20% more gold coins than Cat Basilio did. Overall, Alice donated 10% more gold coins than Cat Basilio. We need to determine the minimum number of gold coins that Alice and Cat Basilio donated to the animal shelter.

Solution

Let's assume that Cat Basilio donated x gold coins to the animal shelter.

According to the problem, Alice donated 25% fewer gold coins than Cat Basilio in the first instance. This means Alice donated (100% - 25%) = 75% of x gold coins.

In the second instance, Alice donated 20% more gold coins than Cat Basilio. This means Alice donated (100% + 20%) = 120% of x gold coins.

Overall, Alice donated 10% more gold coins than Cat Basilio. This means Alice donated (100% + 10%) = 110% of x gold coins.

To find the minimum number of gold coins donated by Alice and Cat Basilio, we need to find the minimum value of x that satisfies the given conditions.

Let's solve the equation: 75% of x + 120% of x = 110% of x

Simplifying the equation: 0.75x + 1.2x = 1.1x 1.95x = 1.1x 0.85x = 0 x = 0

The equation has no solution, which means there is no minimum number of gold coins that Alice and Cat Basilio donated to the animal shelter.

Therefore, the answer is there is no minimum number of gold coins that Alice and Cat Basilio donated to the animal shelter.
