Answer 3

Calculation of Price Difference

To calculate the price difference between a chair and a stool, we can use the given information.

The cost of 3 stools is 420 rubles, and the cost of 2 chairs is 560 rubles.

Let's find out the price of one stool and one chair.

To find the price of one stool, we can divide the total cost of 3 stools (420 rubles) by 3:

Price of one stool = 420 rubles / 3 = 140 rubles.

To find the price of one chair, we can divide the total cost of 2 chairs (560 rubles) by 2:

Price of one chair = 560 rubles / 2 = 280 rubles.

Price Difference and Ratio

Now, let's calculate the price difference between a chair and a stool.

The chair is more expensive than the stool by the difference in their prices:

Price difference = Price of one chair - Price of one stool = 280 rubles - 140 rubles = 140 rubles.

Therefore, the chair is 140 rubles more expensive than the stool.

To find out how many times the stool is cheaper than the chair, we can divide the price of the chair by the price of the stool:

Chair-to-stool ratio = Price of one chair / Price of one stool = 280 rubles / 140 rubles = 2.

Therefore, the stool is 2 times cheaper than the chair.

So, the chair is 140 rubles more expensive than the stool, and the stool is 2 times cheaper than the chair.
