Question

К новогоднему празднику школа покупает каждому ученику по шоколадке.Известно, что если покупать шоколад в упаковке по 20 шоколадок в каждой, то понадобится на 5 упаковок больше, чем упаковок по 24 шоколадки.Сколько учеников в школе?

Answer 1

20х6=24х5=120. Т.е. на одну упаковку придется купить больше, если 120 учеников. 120х5=600. 

Ответ: 600 учеников.

Answer 2

Calculation of the Number of Students in the School

To determine the number of students in the school, we can use the information provided about the purchase of chocolates. Let's break down the given information:

- The school buys one chocolate for each student for the New Year holiday. - If the chocolates are purchased in packs of 20, it requires 5 more packs than if they were purchased in packs of 24.

Let's assume that the number of students in the school is represented by the variable x.

If the chocolates are purchased in packs of 20, the total number of chocolates required would be 20x.

If the chocolates are purchased in packs of 24, the total number of chocolates required would be 24(x + 5).

Since both scenarios require the same number of chocolates, we can set up the following equation:

20x = 24(x + 5)

To solve this equation, we can simplify it:

20x = 24x + 120

120 = 4x

x = 30

Therefore, there are 30 students in the school.
