Problem Analysis

We are given the following information: - The cost of a glass is three times the cost of a cup. - The cup is half the price of the sugar bowl. - The total cost of a glass, a cup, and a sugar bowl is 121 rubles and 11 kopeks.

We need to determine the cost of the sugar bowl.

Solution

Let's assign variables to the unknowns: - Let x be the cost of the cup. - The cost of the glass is three times the cost of the cup, so the cost of the glass is 3x. - The cup is half the price of the sugar bowl, so the cost of the sugar bowl is 2x.

According to the given information, the total cost of the glass, cup, and sugar bowl is 121 rubles and 11 kopeks. We can write this as an equation:

3x + x + 2x = 121 rubles and 11 kopeks

Simplifying the equation, we have:

6x = 121 rubles and 11 kopeks

To solve for x, we divide both sides of the equation by 6:

x = (121 rubles and 11 kopeks) / 6

Now we can calculate the value of x and then find the cost of the sugar bowl.

Calculation

Let's calculate the value of x:

x = (121 rubles and 11 kopeks) / 6

Using a calculator, we find:

x ≈ 20 rubles and 19 kopeks

Now, let's find the cost of the sugar bowl, which is 2x:

Cost of sugar bowl = 2 * x

Substituting the value of x, we have:

Cost of sugar bowl = 2 * (20 rubles and 19 kopeks)

Using a calculator, we find:

Cost of sugar bowl ≈ 40 rubles and 38 kopeks

Answer

The cost of the sugar bowl is approximately 40 rubles and 38 kopeks.

Please note that the actual cost may vary slightly due to rounding during calculations.
