Question

К празднику ученики первого класса купили на 3 букета цветов меньше, чем ученики третьего класса, а ученики второго класса на 5 букетов больше, чем ученики первого. Всего было куплено 110 букета. Сколько букетов было куплено каждым классом?

Answer 1

Пусть первоклассники купили х букетов тогда третьеклассники х+3, а второклассники х+5 всего 110 букетов. получаем уравнение:
х+х+3+х+5=110
3х=110-8
х=102/3
х=34
Первоклашки купили 34 букета
Второклашки 34+5=39 букетов
Третьеклашки 34+3=37

Answer 2

Problem Analysis

We are given the following information: - Students in the first grade bought 3 fewer bouquets than students in the third grade. - Students in the second grade bought 5 more bouquets than students in the first grade. - A total of 110 bouquets were bought.

We need to determine how many bouquets were bought by each grade.

Solution

Let's assume the number of bouquets bought by students in the first grade is x.

According to the given information: - Students in the third grade bought x + 3 bouquets. - Students in the second grade bought x + 5 bouquets.

The total number of bouquets bought is 110, so we can write the equation:

x + (x + 3) + (x + 5) = 110

Simplifying the equation: 3x + 8 = 110

Solving for x: 3x = 102 x = 34

Therefore, students in the first grade bought 34 bouquets, students in the third grade bought 37 bouquets (34 + 3), and students in the second grade bought 39 bouquets (34 + 5).

Answer

Students in the first grade bought 34 bouquets, students in the third grade bought 37 bouquets, and students in the second grade bought 39 bouquets.
