Calculating the Amount of Money

To solve this problem, we can use algebra to represent the given information and then solve for the unknowns.

Let's denote: - x as the amount of money Igor has, - x + 20 as the amount of money Jenya has, and - x + 15 as the amount of money Petya has.

We are given that Jenya has 20 marks more than Igor and 15 marks less than Petya.

So, we can set up the following equations: 1. x + 20 = x + 15 + 15 (Jenya has 20 marks more than Igor and 15 marks less than Petya) 2. x + 20 = x + 30 (Simplify the equation)

Now, we can solve for x: 3. x = x + 30 - 20 (Subtract 20 from both sides) 4. x = x + 10 (Simplify the equation)

This equation doesn't make sense, as it implies that 0 = 10. It seems there might be an error in the given information or the problem setup.

Let's re-evaluate the given information and equations to ensure accuracy.
