Answer 1

Problem Analysis

The problem states that a buyer gave the seller 100 tenge and received as much change as the number of liters of milk purchased. We need to find the cost of one liter of milk, knowing that it is more than 10 tenge and expressed as an even number.

Solution

Let's assume that the cost of one liter of milk is x tenge. Since the buyer received as much change as the number of liters of milk purchased, the change received by the buyer is also x tenge.

We can set up the equation: 100 - x = x

Simplifying the equation: 100 = 2x

Solving for x: x = 100 / 2 x = 50

Therefore, the cost of one liter of milk is 50 tenge.

Answer

The cost of one liter of milk is 50 tenge.
