Question

В школе равное число девочек и мальчиков . Я принес 234 ореха и каждому мальчику досталось по 5 орехов каждой девочке по 4 ореха. Но девочки обиделись и в другой раз я принес столько орехов что всем досталось по 6 . Сколько орехов я принес?

Answer 1

Пусть х количество мальчиков, тогда х количество девочек, т. к. по условию они равны. Зная, что всего орехов 234. составим уравнение
5х+4х=234
9х=234
х=234/9
х=26 количество мальчиков, количество девочек
(26+26)*6=312 орехов принес в другой раз

Answer 2

Problem Analysis

In the given problem, there is an equal number of boys and girls in school. The user brought 234 nuts and distributed 5 nuts to each boy and 4 nuts to each girl. However, the girls got upset, so the user brought more nuts the next time and distributed 6 nuts to each person. The question is how many nuts did the user bring the second time?

Solution

To find the number of nuts the user brought the second time, we need to calculate the total number of boys and girls in the school. Then we can calculate the total number of nuts distributed in both scenarios and find the difference.

Let's calculate the number of nuts the user brought the second time step by step:

1. Calculate the number of boys and girls in the school: - Since there is an equal number of boys and girls, we can divide the total number of nuts by the sum of the nuts given to each boy and girl. - Let's denote the number of boys and girls as x. - We can set up the following equation: 5x + 4x = 234. - Solving this equation will give us the value of x.

2. Calculate the number of nuts distributed the second time: - In the second scenario, each person received 6 nuts. - The total number of nuts distributed can be calculated as 6 * (number of boys + number of girls).

3. Calculate the difference in the number of nuts brought between the two scenarios: - The difference can be calculated as number of nuts distributed in the second scenario - number of nuts distributed in the first scenario.

Let's calculate the number of nuts the user brought the second time using the above steps.

Calculation

1. Calculate the number of boys and girls in the school: - We can solve the equation 5x + 4x = 234 to find the value of x. - Simplifying the equation, we get 9x = 234. - Dividing both sides of the equation by 9, we get x = 26.

2. Calculate the number of nuts distributed the second time: - In the second scenario, each person received 6 nuts. - The total number of nuts distributed can be calculated as 6 * (number of boys + number of girls). - Substituting the value of x (26) into the equation, we get 6 * (26 + 26) = 312.

3. Calculate the difference in the number of nuts brought between the two scenarios: - The difference can be calculated as number of nuts distributed in the second scenario - number of nuts distributed in the first scenario. - Substituting the values, we get 312 - 234 = 78.

Answer

The user brought 78 nuts the second time.
