Answer 2

Problem Analysis

We are given that Sasha, Kolya, and Sereja collected a total of 51 cups of raspberries. Sereja collected twice as many cups as Sasha, and Kolya collected three cups more than Sasha. We need to determine how many cups each of the boys collected.

Solution

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

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

The total number of cups collected 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 raspberries, Sereja collected 2 * 12 = 24 cups, and Kolya collected 12 + 3 = 15 cups.

Answer

Sasha collected 12 cups of raspberries, Kolya collected 15 cups, and Sereja collected 24 cups.
