Problem Analysis

To solve this problem, we need to find the number of coins worth 20 tenge that Aruzhan has. We are given that Aliya had 300 tenge, and Aruzhan had some coins worth 20 tenge. When Aliya received an additional 100 tenge, they both had an equal amount of money. We need to determine the number of coins worth 20 tenge that Aruzhan has.

Solution

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

Initially, Aliya had 300 tenge, and Aruzhan had x coins worth 20 tenge.

When Aliya received an additional 100 tenge, the total amount of money they both had became equal.

We can set up the following equation to represent this situation:

300 + 100 = x * 20

Simplifying the equation:

400 = 20x

To solve for x, we divide both sides of the equation by 20:

x = 400 / 20

Calculating the value of x:

x = 20

Therefore, Aruzhan has 20 coins worth 20 tenge.

Answer

Aruzhan has 20 coins worth 20 tenge.
