Problem Statement

В воскресенье музей посетили 3 дошкольника, школьников на 4 больше, а студентов столько, сколько дошкольников и школьников вместе. Сколько студентов посетило музей?

Solution

Let's break down the information given in the problem statement:

- В воскресенье музей посетили 3 дошкольника (3 preschoolers visited the museum). - Школьников на 4 больше (There are 4 more schoolchildren). - Студентов столько, сколько дошкольников и школьников вместе (There are as many students as preschoolers and schoolchildren combined).

To find the number of students who visited the museum, we need to determine the total number of preschoolers and schoolchildren, and then add 4 to that sum.

Let's denote: - Д - number of дошкольников (preschoolers) - Ш - number of школьников (schoolchildren) - С - number of студентов (students)

Based on the given information, we can write the following equations:

1. Д = 3 (Three preschoolers visited the museum). 2. Ш = Д + 4 (The number of schoolchildren is 4 more than the number of preschoolers). 3. С = Д + Ш (The number of students is equal to the sum of preschoolers and schoolchildren).

To find the value of С, we need to solve these equations.

Substituting equation 1 into equation 2, we get: Ш = 3 + 4 = 7

Substituting equations 1 and 2 into equation 3, we get: С = 3 + 7 = 10

Therefore, 10 students visited the museum.

Answer

The number of students who visited the museum is 10.
