Problem Analysis

We are given the following information: - Sasha weighs 1.2 times more than Vanya. - Vanya weighs 4.4 kg less than Vasya. - The total weight of the three boys is 1.5 centners (1.5 * 100 kg).

We need to find the weight of each boy.

Solution

Let's assume the weight of Vanya is x kg.

According to the given information: - Sasha weighs 1.2 times more than Vanya, so Sasha's weight is 1.2x kg. - Vanya weighs 4.4 kg less than Vasya, so Vasya's weight is x + 4.4 kg.

The total weight of the three boys is 1.5 centners (150 kg). Therefore, we can write the equation:

x + 1.2x + (x + 4.4) = 150

Simplifying the equation:

3.2x + 4.4 = 150

Subtracting 4.4 from both sides:

3.2x = 145.6

Dividing both sides by 3.2:

x = 45.5

So, Vanya weighs 45.5 kg.

Using this information, we can find the weights of Sasha and Vasya:

- Sasha weighs 1.2 times more than Vanya, so Sasha's weight is 1.2 * 45.5 = 54.6 kg. - Vasya's weight is x + 4.4 = 45.5 + 4.4 = 49.9 kg.

Therefore, the weights of the boys are as follows: - Vanya weighs 45.5 kg. - Sasha weighs 54.6 kg. - Vasya weighs 49.9 kg.

Note: The weights are rounded to one decimal place.

Answer

Based on the given information, the weights of the boys are as follows: - Vanya weighs approximately 45.5 kg. - Sasha weighs approximately 54.6 kg. - Vasya weighs approximately 49.9 kg.
