Question

Самат арман и дархан втроем собрали 78 марки марок арман собрал в 3 раза больше марок. а дархан в 2,5 раза больше чем самат сколько марок собрал? сколько марок сабрал дархан?

Answer 1

Х - собрал марок Самат
3х - собрал марок Армат
2,5х - собрал марок Дархан
х + 3х + 2,5х = 78
6,5х = 78
х = 78 / 6,5
х = 12 - собрал марок Самат
Дархан собрал марок - 2,5х то есть 12 * 2,5 = 30 марок

Answer 2

Solution:

To solve this problem, we can use a system of equations to represent the given information and then solve for the number of stamps each person collected.

Let's denote: - S as the number of stamps Samat collected, - A as the number of stamps Arman collected, and - D as the number of stamps Darhan collected.

We are given the following information: 1. Samat, Arman, and Darhan collected a total of 78 stamps: S + A + D = 78. 2. Arman collected 3 times more stamps than Samat: A = 3S. 3. Darhan collected 2.5 times more stamps than Samat: D = 2.5S.

We can use these equations to solve for the number of stamps each person collected.

First, we can express the number of stamps Arman and Darhan collected in terms of S: - Arman: A = 3S - Darhan: D = 2.5S

Now, we can substitute these expressions into the total number of stamps equation: S + 3S + 2.5S = 78

Solving for S: 6.5S = 78 S = 78 / 6.5 S = 12

So, Samat collected 12 stamps.

Now, we can find the number of stamps Arman and Darhan collected: - Arman: A = 3S = 3 * 12 = 36 stamps - Darhan: D = 2.5S = 2.5 * 12 = 30 stamps

Answer:

- Samat collected 12 stamps. - Darhan collected 30 stamps.
