Question

цена вещи упала на 500 сумов а затем новая цена упала Еще на 20% весь стал стоить 4.000 сумов Найдите первоначальную цену вещи​

Answer 1

Ответ:

Изначально вещь стоила 5500 сумов

Пошаговое объяснение:

1)Составим пропорцию:

4000 - 80%

       x - 100%

$\displaystyle x=\frac{4000*100}{80} =5000$

2) 5000+500 = 5500

Answer 2

Ответ:

5 500 сумов первоначальная цена

Пошаговое объяснение:

Пусть первоначальная цена вещи х сумов, тогда:

20% = 20/100 = 0,2

х - 500 сумов - цена упала на 500 сумов

0,2(х-500) сумов - сумма снижения ещё на 20%

Составим уравнение:

(х-500) - 0,2(х-500) = 4000

х-500-0,2х+100 = 4000

0,8х = 4000+500-100

0,8х = 4400

х = 4400/0,8

х = 5 500 сумов первоначальная цена

Answer 3

Calculation of the Initial Price

To find the initial price of the item, we can work backward from the final price of 4,000 sūms. We know that the final price is 20% less than the price after it dropped by 500 sūms. Let's break down the calculation step by step:

1. The final price is 4,000 sūms. 2. The final price is 20% less than the price after it dropped by 500 sūms. 3. Let's assume the price after it dropped by 500 sūms is P. 4. The final price is 20% less than P, which means it is equal to 80% of P. 5. We can express this relationship as an equation: 0.8P = 4,000. 6. To find P, we divide both sides of the equation by 0.8: P = 4,000 / 0.8. 7. Solving the equation, we find that P is equal to 5,000 sūms.

Therefore, the initial price of the item was 5,000 sūms.
