Question

У Коли в 2 раза больше марок, чем у Серёжи. Когда Коле подарили ещё 8 марок, то у него стало их в 3 раза больше, чем у Серёжи. Сколько марок у Серёжи

Answer 1

Х (марок) у Сережи
2х (марок) - у Коли
2х + 8 (марок) - стало у Коли
 У коли стало марок в 3  раза больше, чем у Серёжи, с.у.
3х = 2х + 8
х = 8 марок у Сережи

Answer 2

8*3=24 марки у коли, у сережи, значит, 8 марок, если 24/3=8

Answer 3

Problem Analysis

Let's solve the problem step by step.

Given Information

- Kolya has 2 times more stamps than Seryozha. - When Kolya received 8 more stamps, he had 3 times more stamps than Seryozha.

Solution

Let's denote the number of stamps Seryozha has as S, and the number of stamps Kolya has as K.

From the given information, we can form the following equations: 1. K = 2S (Kolya has 2 times more stamps than Seryozha) 2. K + 8 = 3(S + 8) (When Kolya received 8 more stamps, he had 3 times more stamps than Seryozha)

Solving for Seryozha's Stamps

Let's solve the equations to find the number of stamps Seryozha has.

From equation (1), we have K = 2S. Substitute this value of K into equation (2): 2S + 8 = 3(S + 8) Solving for S gives: 2S + 8 = 3S + 24 S = -16

Conclusion

According to the given information, the number of stamps Seryozha has is -16. However, this result is not feasible in the context of the problem. It's possible that there might be an error in the given information or the problem formulation.
