Problem Analysis

We are given that Ali has 300 tenge, while Aruzhan has several coins worth 20 tenge each. When Ali gives Aruzhan an additional 100 tenge, they both have an equal amount of money. We need to determine how many coins worth 20 tenge Aruzhan has.

Solution

Let's assume that Aruzhan has x coins worth 20 tenge each.

Initially, Ali has 300 tenge and Aruzhan has x coins worth 20 tenge each.

When Ali gives Aruzhan an additional 100 tenge, Ali will have 300 - 100 = 200 tenge, and Aruzhan will have x coins worth 20 tenge each plus 100 tenge.

Since they both have an equal amount of money, we can set up the following equation:

200 = x * 20 + 100

Simplifying the equation, we get:

200 = 20x + 100

Subtracting 100 from both sides:

100 = 20x

Dividing both sides by 20:

x = 5

Therefore, Aruzhan has 5 coins worth 20 tenge each.

Answer

Aruzhan has 5 coins worth 20 tenge each.
