Answer 2

Problem:

We are given that the price of a table (стол) is 9 times more expensive than a chair (стул). We also know that the table is 240 rubles more expensive than the chair. We need to find the prices of the table and the chair.

Solution:

Let's assume the price of the chair is x rubles. Since the table is 9 times more expensive than the chair, the price of the table can be represented as 9x rubles.

According to the given information, the table is 240 rubles more expensive than the chair. We can express this as an equation:

9x - x = 240

Simplifying the equation, we have:

8x = 240

To find the value of x, we divide both sides of the equation by 8:

x = 240 / 8 = 30

Therefore, the price of the chair is 30 rubles.

To find the price of the table, we substitute the value of x into the equation:

9x = 9 * 30 = 270

Therefore, the price of the table is 270 rubles.

So, the chair costs 30 rubles and the table costs 270 rubles.

Equation: 9x - x = 240

Solution: x = 30 (price of the chair) 9x = 270 (price of the table)

Therefore, the chair costs 30 rubles and the table costs 270 rubles.
