Problem Analysis

We are given two packages of pencils. One package contains 12 pencils, and the other package contains 36 more pencils than the first package. The total cost of both packages is 420 rubles. We need to find the cost of each package.

Solution

Let's assume the cost of the first package is x rubles. Since the second package contains 36 more pencils, its cost will be x + 36 rubles.

The total cost of both packages is 420 rubles. Therefore, we can write the equation:

x + (x + 36) = 420

Simplifying the equation:

2x + 36 = 420

Subtracting 36 from both sides:

2x = 420 - 36

2x = 384

Dividing both sides by 2:

x = 384 / 2

x = 192

So, the cost of the first package is 192 rubles.

The cost of the second package is x + 36 = 192 + 36 = 228 rubles.

Answer

Each package of pencils costs 192 rubles and 228 rubles respectively.
