Question

Рыбаки во вторник наловили рыбу на 30% больше чем в понедельник. В среду они наловили 468 рыб что на 10% меньше чем во вторник. Сколько рыбы наловили рыбаки в понедельник?

Answer 1

100% = х  -  в понедельник

100% + 30% = 130% = 1,3х  -  во вторник

90% от 130% (от вторника) = 0,9 * 1,3х = 1,17х -  в среду

468 : 1,17 = 400 рыб - в понедельник

Ответ: в понедельник рыбаки наловили 400 рыб.

Или решение с конца задачи:

468 рыб - это 90% от вторника:

1) 468 : 0,9 = 520 рыб - наловили во вторник

520 рыб - это 130% от понедельника:

2) 520 : 1,3 = 400 рыб - наловили в понедельник - ответ.

Answer 2

Calculation of Fish Caught by Fishermen

To determine the amount of fish caught by the fishermen on Monday, we can use the information provided.

According to the given information: - On Tuesday, the fishermen caught 30% more fish than on Monday. - On Wednesday, they caught 468 fish, which is 10% less than on Tuesday.

Let's calculate the amount of fish caught on Monday.

Step 1: Calculate the amount of fish caught on Tuesday. - Let's assume the amount of fish caught on Monday is x. - On Tuesday, the fishermen caught 30% more fish than on Monday, which means they caught 1.3x fish.

Step 2: Calculate the amount of fish caught on Wednesday. - On Wednesday, the fishermen caught 468 fish, which is 10% less than on Tuesday. - This can be represented as 0.9 * (1.3x) = 468.

Now, let's solve the equation to find the value of x, which represents the amount of fish caught on Monday.

0.9 * (1.3x) = 468

Simplifying the equation:

1.17x = 468

Dividing both sides of the equation by 1.17:

x = 468 / 1.17

Calculating the value:

x ≈ 400

Therefore, the fishermen caught approximately 400 fish on Monday.

Please note that the calculation is an approximation, as the given information does not provide exact values.
