Answer 3

Problem Analysis

We are given that the number of stamps (marok) owned by Dima is twice the number owned by Alyosha. We also know that the total number of stamps between the two boys is 150. We need to determine how many stamps each boy has using an equation.

Solution

Let's assume that the number of stamps Alyosha has is x. According to the problem, Dima has twice the number of stamps as Alyosha, so Dima has 2x stamps.

The total number of stamps between the two boys is given as 150, so we can set up the following equation:

x + 2x = 150

Simplifying the equation, we get:

3x = 150

Dividing both sides of the equation by 3, we find:

x = 50

So Alyosha has 50 stamps. Since Dima has twice the number of stamps as Alyosha, Dima has:

2 * 50 = 100 stamps

Therefore, Alyosha has 50 stamps and Dima has 100 stamps.

Answer

Alyosha has 50 stamps and Dima has 100 stamps.
