Problem Analysis

To find the cost of 12 sets of colored pencils, we need to determine the cost of one set of colored pencils. We are given that four identical sets of colored pencils cost 820 rubles. We can use this information to calculate the cost of one set and then multiply it by 12 to find the total cost of 12 sets.

Calculation

Let's calculate the cost of one set of colored pencils using the given information.

The cost of four identical sets of colored pencils is 820 rubles.

To find the cost of one set, we can divide the total cost by the number of sets:

820 rubles / 4 sets = 205 rubles per set.

Now that we know the cost of one set, we can calculate the cost of 12 sets by multiplying the cost per set by the number of sets:

205 rubles per set * 12 sets = 2460 rubles for 12 sets.

Therefore, 12 sets of colored pencils will cost 2460 rubles.

Answer

The cost of 12 sets of colored pencils is 2460 rubles.
