Answer 2

Problem Analysis

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

Solution

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

According to the problem, Sergey collected twice as many raspberries as Sasha, so Sergey collected 2x cups of raspberries.

Kolya collected 3 cups more than Sasha, so Kolya collected x + 3 cups of raspberries.

The total number of cups of raspberries collected by all three boys is given as 51.

Therefore, 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

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

Answer

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