Question

Товар стоил 4000 тенге. Цену сначала уценили на 10% затем на 20%.На сколько тенге изменилась цена товара? ​

Answer 1

1) 4000 : 100 · 10 = 400 (тг) - на столько снизилась цена в первый раз;

2) 4000 - 400 = 3600 (тг) - цена товара после уценки на 10%;

3) 3600 : 100 · 20 = 720 (тг) - на столько снизилась цена во второй раз;

4) 3600 - 720 = 2880 (тг) - цена товара после уценки на 20%;

5) 4000 - 2880 = 1120 (тг) - на столько снизилась цена товара после двух уценок.

Ответ: снизалась на 1120 тенге.

Answer 2

Calculation of the Price Change

To calculate the change in the price of the item, we need to apply the discounts successively.

The initial price of the item was 4000 tenge. First, the price was reduced by 10%, and then it was further reduced by 20%.

Let's calculate the price change step by step:

1. First discount of 10%: - 10% of 4000 tenge is 400 tenge. - Subtracting 400 tenge from the initial price, we get 3600 tenge.

2. Second discount of 20%: - 20% of 3600 tenge is 720 tenge. - Subtracting 720 tenge from the discounted price, we get 2880 tenge.

Calculation Result

The price of the item has decreased by 1120 tenge. The final price of the item is 2880 tenge.
