Problem Analysis

We are given that there are between 25 and 35 students in a class, and they were given 87 pencils evenly. We need to determine 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 can divide the total number of pencils by the number of students. Let's calculate it:

Total number of pencils = 87 Number of students = Between 25 and 35

To find out how many pencils each student received, we divide the total number of pencils by the number of students:

Number of pencils each student received = Total number of pencils / Number of students

Let's calculate it:

Number of pencils each student received = 87 / Number of students

To find the number of students, we can try different values within the given range and see which one gives us a whole number of pencils for each student.

Calculation

Let's calculate the number of pencils each student received for different numbers of students within the given range:

For 25 students: Number of pencils each student received = 87 / 25 = 3.48

For 26 students: Number of pencils each student received = 87 / 26 = 3.35

For 27 students: Number of pencils each student received = 87 / 27 = 3.22

For 28 students: Number of pencils each student received = 87 / 28 = 3.11

For 29 students: Number of pencils each student received = 87 / 29 = 3

For 30 students: Number of pencils each student received = 87 / 30 = 2.9

For 31 students: Number of pencils each student received = 87 / 31 = 2.81

For 32 students: Number of pencils each student received = 87 / 32 = 2.72

For 33 students: Number of pencils each student received = 87 / 33 = 2.64

For 34 students: Number of pencils each student received = 87 / 34 = 2.56

For 35 students: Number of pencils each student received = 87 / 35 = 2.49

Answer

Based on the calculations, we can see that if there are 29 students in the class, each student will receive 3 pencils. Therefore, each student received 3 pencils and there are 29 students in the class.
