Question

У Димы и сашы всего 570 тенге,На 1/4 своих денег Дима купил албом,а Саша на 1/6 своих денег купил книгу.После у каждого из них осталось одинаковая сумма денег.Сколько денег у Димы первоначально было?

Answer 1

х-1/4х=3/4х-осталось у Димы.

(570-х)-(570-х):6=5*(570-х):6-осталось у Саши.

1)3/4х=5*(570-х):6

18х=20*(570-х)

18х+20х=11400

38х=11400

х=11400:38

х=300тенге-было у Димы.

 

570-300=270тенге-было у Саши.

Answer 2

3/4х-осталось у Димы.

5/6*(570-х)-осталось у Саши

1)3/4х=5/6*(570-х)

3/4х=475-5/6х

19/12х=475

х=475*12:19

х=300тенге-было у Димы.

2)570-300=270тенге-было у саши.

 

 

Answer 3

Problem Analysis

We are given that Dima and Sasha have a total of 570 tenge. Dima spends 1/4 of his money on an album, while Sasha spends 1/6 of his money on a book. After their purchases, they both have the same amount of money left. We need to determine how much money Dima initially had.

Solution

Let's assume that Dima initially had x tenge.

Dima spends 1/4 of his money on an album, which is (1/4) * x = x/4 tenge.

Sasha spends 1/6 of his money on a book, which is (1/6) * x = x/6 tenge.

After their purchases, they both have the same amount of money left. Let's denote this amount as y tenge.

So, we can set up the following equation:

x - (x/4) = y x - (x/6) = y

Simplifying these equations, we get:

(3/4) * x = y (5/6) * x = y

Since both equations are equal to y, we can set them equal to each other:

(3/4) * x = (5/6) * x

To solve for x, we can cross-multiply:

6 * (3/4) * x = 4 * (5/6) * x 18 * x = 20 * x

Subtracting 20x from both sides, we get:

18 * x - 20 * x = 0 -2 * x = 0

Dividing both sides by -2, we get:

x = 0

However, this would mean that Dima initially had 0 tenge, which is not possible. Therefore, there seems to be an error in the given information or the problem statement.
