Problem Analysis

We are given the following information: - The ruler costs 3 rubles. - The pencils are 6 times more expensive than the ruler. - The pen is 2 times cheaper than the pencils.

We need to find: - The cost of the pencils. - The cost of the pen. - The price difference between the pencils and the ruler. - The total cost of the purchase.

Solution

Let's solve the problem step by step.

1. Find the cost of the pencils: - The pencils are 6 times more expensive than the ruler. - Therefore, the cost of the pencils is 6 times the cost of the ruler. - The ruler costs 3 rubles, so the pencils cost 3 * 6 = 18 rubles.

2. Find the cost of the pen: - The pen is 2 times cheaper than the pencils. - Therefore, the cost of the pen is half the cost of the pencils. - The pencils cost 18 rubles, so the pen costs 18 / 2 = 9 rubles.

3. Find the price difference between the pencils and the ruler: - The pencils cost 18 rubles and the ruler costs 3 rubles. - Therefore, the pencils are 18 - 3 = 15 rubles more expensive than the ruler.

4. Find the total cost of the purchase: - The ruler costs 3 rubles, the pencils cost 18 rubles, and the pen costs 9 rubles. - Therefore, the total cost of the purchase is 3 + 18 + 9 = 30 rubles.

Answer

Based on the given information, the pencils cost 18 rubles, the pen costs 9 rubles, the pencils are 15 rubles more expensive than the ruler, and the total cost of the purchase is 30 rubles.
