Question

На базе было 320 т рыбы.В первый день вывезли в 3 раза больше,чем во второй,а в третий- столько ,сколько в первый и второй дни вместе.Сколько тонн рыбы вывезли в каждый день?

Answer 1

Вывезли во второй день х
вывезли в первый день 3х
вывезли в третий день х+3х=4х
всего вывезли 320 т
составим уравнение
х+3х+4х=320
8х=320
х=320:8
х=40 т во второй день
40*3=120 т в первый день
40*4=160 т в третий день

Problem Analysis

To solve this problem, we need to determine the amount of fish that was taken out each day. We are given the following information:

- On the first day, they took out three times more fish than on the second day. - On the third day, they took out the same amount of fish as the combined amount taken out on the first and second days.

We are also given that there were initially 320 tons of fish.

Solution

Let's solve this problem step by step.

1. Let's assume that the amount of fish taken out on the second day is x tons.

2. On the first day, they took out three times more fish than on the second day. So, the amount of fish taken out on the first day is 3x tons.

3. On the third day, they took out the same amount of fish as the combined amount taken out on the first and second days. So, the amount of fish taken out on the third day is (3x + x) = 4x tons.

4. The total amount of fish taken out over the three days is 320 tons. So, we can write the equation: x + 3x + 4x = 320.

5. Simplifying the equation, we get: 8x = 320.

6. Solving for x, we find: x = 40.

Now that we have the value of x, we can calculate the amount of fish taken out on each day:

- On the first day: 3x = 3 * 40 = 120 tons. - On the second day: x = 40 tons. - On the third day: 4x = 4 * 40 = 160 tons.

Answer

Therefore, the amount of fish taken out each day is as follows:

- On the first day: 120 tons. - On the second day: 40 tons. - On the third day: 160 tons.
