Х - Саша
2х - Сережа
х+3 - Коля
51 ст. - всего

1) х+2х+х+3=51
    4х+3=51
    4х=51-3

    х=48:4
    х=12 ст. - собрал Саша
2) 2х=2*12=24 ст. - собрал Сережа

Answer 2

Problem Analysis

We are given that Sasha, Kolya, and Sergey collected a total of 51 cups of berries. Sergey collected twice as many cups as Sasha, and Kolya collected 3 more cups than Sasha. We need to determine how many cups each boy collected.

Solution

Let's assume that Sasha collected x cups of berries.

According to the given information: - Sergey collected twice as many cups as Sasha, so Sergey collected 2x cups. - Kolya collected 3 more cups than Sasha, so Kolya collected x + 3 cups.

The total number of cups collected by all three boys is 51, so we can write the equation:

x + 2x + (x + 3) = 51

Simplifying the equation:

4x + 3 = 51

Subtracting 3 from both sides:

4x = 48

Dividing both sides by 4:

x = 12

Therefore, Sasha collected 12 cups of berries, Sergey collected 2 * 12 = 24 cups, and Kolya collected 12 + 3 = 15 cups.

Answer

Sasha collected 12 cups of berries, Sergey collected 24 cups, and Kolya collected 15 cups.
