Answer 1

1)21000-21000×0,08=19320 тг/шт цена после первого снижения цены.

19320-19320×0,15=16422 тг/шт цена после второго снижения цены.

Ответ 16422 тг/шт цена после второго снижения цены.

2)60%=0,6 части ; 40%=0,4 части

10 1/4*0,6=10,25*0,6=6,15т ( продали овощей в первый день)

2) 6,15*0,4=2,46т( продали во второй день)

3) 6,15т+2,46т=8,61т ( продали за два дня)

4)10,25т-8,61т=1,64т  (осталось продать).

Answer 2

Problem 863.1:

The price of a cell phone is 21,000 tenge per unit. It was reduced by 8%, and after some time, the new price was reduced again by 15%. What is the price of the cell phone after the second reduction?

To solve this problem, we need to calculate the final price of the cell phone after both reductions.

Let's start by calculating the price after the first reduction. To do this, we need to find 8% of the original price and subtract it from the original price.

Step 1: Calculate the price after the first reduction:

Original price = 21,000 tenge Reduction percentage = 8%

Reduction amount = (8/100) * 21,000 = 1,680 tenge Price after the first reduction = 21,000 - 1,680 = 19,320 tenge

Now, let's calculate the price after the second reduction. We'll use the same approach as before.

Step 2: Calculate the price after the second reduction:

Price after the first reduction = 19,320 tenge Reduction percentage = 15%

Reduction amount = (15/100) * 19,320 = 2,898 tenge Price after the second reduction = 19,320 - 2,898 = 16,422 tenge

Therefore, the price of the cell phone after the second reduction is 16,422 tenge.
