Question

Магазин продав за 3 дні 460 кг овочів. За перший день було продано овочів на 20 кг менше, а за третій - в 1,2 разу більше, ніж за другий. Скільки овочів продав магазин за кожний день окремо?

Answer 1

Пусть во второй день продали Хкг,тогда в 1-й  Х-20 (кг), а в 3-й   1,2Х

сОСТАВИМ УРАВНЕНИЕ:

Х-20+Х+1,2Х=460   3,2 Х=460+20   3,2Х=480     Х=480/3,2    Х=150(кгГ)-продали во 2-й день, тогда в 1-й: 150-20= 130 (кг),

в 3-й: 1,2*150=180 (кг).

Answer 2

1д.- x-20

2- x

3- 1.2x

 

(x-20)+x+1.2=460

x-20+x+1.2=460

3.2x=480

x=480:3.2

 

1день=130

2день=150

3день=1.2 * 150=180

Answer 3

Problem Analysis

To solve this problem, we need to determine how many vegetables were sold by the store each day. We are given that the store sold 460 kg of vegetables over a period of 3 days. On the first day, they sold 20 kg less than the total amount sold. On the third day, they sold 1.2 times more than the amount sold on the second day. We need to find the amount sold on each day separately.

Solution

Let's assume the amount of vegetables sold on the second day is x kg.

According to the given information: - On the first day, the store sold x + 20 kg of vegetables. - On the second day, the store sold x kg of vegetables. - On the third day, the store sold 1.2x kg of vegetables.

The total amount of vegetables sold over the 3 days is 460 kg. Therefore, we can write the equation:

(x + 20) + x + 1.2x = 460

Simplifying the equation:

3.2x + 20 = 460

Subtracting 20 from both sides:

3.2x = 440

Dividing both sides by 3.2:

x = 137.5

Now we can calculate the amount of vegetables sold on each day:

- On the first day: x + 20 = 137.5 + 20 = 157.5 kg - On the second day: x = 137.5 kg - On the third day: 1.2x = 1.2 * 137.5 = 165 kg

Therefore, the store sold 157.5 kg of vegetables on the first day, 137.5 kg on the second day, and 165 kg on the third day.

Answer

The store sold the following amounts of vegetables each day: - First day: 157.5 kg - Second day: 137.5 kg - Third day: 165 kg
