Answer 1

Задача решается методом подбора.
Допустим что каждому ученику досталось по 3 карандаша.

Answer 2

Problem Analysis

We are given that there are between 25 and 35 students in a class. They were given 87 pencils to distribute equally among themselves. We need to find out how many pencils each student received and the total number of students in the class.

Solution

To find out how many pencils each student received, we divide the total number of pencils by the number of students. Let's denote the number of students as N and the number of pencils each student received as P.

We can set up the following equation: N * P = 87

To find the values of N and P, we need to find two numbers that multiply to give 87. We can start by checking the factors of 87.

Calculation

The factors of 87 are: 1, 3, 29, 87

Since the number of students in the class is between 25 and 35, we can eliminate the factors 1 and 3. Therefore, the possible values for N are 29 and 87.

Let's calculate the number of pencils each student received for both cases:

For N = 29: P = 87 / 29 = 3

For N = 87: P = 87 / 87 = 1

Since the number of pencils each student received cannot be 1, we can conclude that there are 29 students in the class and each student received 3 pencils.

Answer

Each student in the class received 3 pencils. There are 29 students in the class.
