1 часть=80:5=16 марок у Сережи
3*16=48 марок у Васи
48*2=96 марок у Коли

Answer 2

Problem Analysis

We are given the following information: - Sergey has 3 times fewer stamps than Vasya. - Kolya has 2 times more stamps than Vasya. - Kolya has 80 more stamps than Sergey.

We need to determine the number of stamps each person has.

Solution

Let's assume that Vasya has x stamps. Based on the given information, we can determine the number of stamps for Sergey and Kolya.

- Sergey has 3 times fewer stamps than Vasya, so Sergey has x/3 stamps. - Kolya has 2 times more stamps than Vasya, so Kolya has 2x stamps. - Kolya has 80 more stamps than Sergey, so 2x = x/3 + 80.

To solve this equation, we can multiply both sides by 3 to eliminate the fraction:

6x = x + 240

Simplifying the equation:

5x = 240

Dividing both sides by 5:

x = 48

Therefore, Vasya has 48 stamps, Sergey has 16 stamps (3 times fewer than Vasya), and Kolya has 96 stamps (2 times more than Vasya and 80 more than Sergey).

Answer

Based on the given information, Vasya has 48 stamps, Sergey has 16 stamps, and Kolya has 96 stamps.
