Question

три студента получили стипендию.Первый получил 0,9 той суммы,который получил второй студент,и еще 4200 тг,а третий студент получил 0,9 той суммы,который получил второй,и еще 1200 тг .Сколько тенге получил каждый студент,если известно,что второй и третий получили поровну?

Answer 1

Х  тг - 2 студент получил
0,9х+4200  - 1 студ.
0,9х+1200  - 3 студ.
х=0,9х+1200
0,1х=1200
х=12000  - 2 студ.
1 студ.  -  0,9*12000+4200=15000
3 студ.  - 0,9*1200+1200=12000

Answer 2

Problem Analysis

We are given that three students received a scholarship. The first student received 0.9 times the amount received by the second student, plus an additional 4200 tenge. The third student received 0.9 times the amount received by the second student, plus an additional 1200 tenge. We need to determine how much money each student received, knowing that the second and third students received the same amount.

Solution

Let's assume that the amount received by the second student is x tenge.

According to the given information: - The first student received 0.9 times x, plus 4200 tenge. - The third student received 0.9 times x, plus 1200 tenge.

To find the amount received by each student, we can set up the following equations:

First student: 0.9x + 4200 = amount received by the first student Third student: 0.9x + 1200 = amount received by the third student

Since the second and third students received the same amount, we can set up the equation:

0.9x + 4200 = 0.9x + 1200

Simplifying the equation, we get:

4200 = 1200

This equation is not possible to solve because it leads to a contradiction. Therefore, there is no solution to this problem.

Conclusion

Based on the given information, it is not possible to determine how much money each student received because the equations lead to a contradiction.
