Question

Трем толстякам принесли 30 пирожных, поровну каждому. Первый съел несколько пирожных, второй съел столько, сколько осталось у первого, а третий съел столько, сколько съели первый и второй вместе. Сколько пирожных осталось у Трёх толстяков

Answer 1

делим кол-во пирожных 30 на трех толстяков. каждый получил по 30:3=10 пирожных. Если второй съел столько, сколько осталось у первого, то значит вместе они съели 10 пирожных. следовательно, третий съел 10 пирожных. т.е. всего они съели 10+10=20 пирожных. а осталось у них 30-20=10 пирожных.

ответ: 10  пирожных осталось у Трёх толстяков

Answer 2

Problem Analysis

Three overweight individuals are given 30 pastries, distributed equally among them. The first person eats some of the pastries, the second person eats the remaining pastries from the first person, and the third person eats the combined amount eaten by the first and second persons. The question is how many pastries are left for the three individuals.

Solution

Let's break down the problem step by step:

1. The three individuals are given 30 pastries, distributed equally among them. This means each person initially receives 30/3 = 10 pastries. 2. The first person eats some of the pastries. 3. The second person eats the remaining pastries from the first person. 4. The third person eats the combined amount eaten by the first and second persons.

To find out how many pastries are left, we need to calculate the number of pastries eaten by each person and subtract that from the initial number of pastries.

Let's calculate the number of pastries eaten by each person:

1. The first person eats some pastries. 2. The second person eats the remaining pastries from the first person. 3. The third person eats the combined amount eaten by the first and second persons.

Let's denote the number of pastries eaten by the first person as x.

The second person eats the remaining pastries from the first person, which is 10 - x.

The third person eats the combined amount eaten by the first and second persons, which is x + (10 - x) = 10.

To find the value of x, we can solve the equation:

x + (10 - x) = 10

Simplifying the equation, we get:

10 = 10

This equation is true for any value of x. Therefore, we cannot determine the exact number of pastries eaten by each person.

However, we can determine the number of pastries left for the three individuals. Since each person initially received 10 pastries, and we don't know how many pastries were eaten, we can conclude that there are 10 pastries left for the three individuals.

Answer

There are 10 pastries left for the three overweight individuals.

Note: The exact number of pastries eaten by each person cannot be determined based on the given information.
