Question

Одна банка трьох літрова а друга пяти літрова як за допомогою цих банок налити в глечик 4 літра води з водопровідного крана

Answer 1

Наполнить 3-литровую банку и вылить из нее воду в 5-литровую. 

Повторно наполнить 3-литровую банку и перелить воду в 5-литровую до её заполнения.  

В 3-литровой останется 1 литр воды. (3+3-5=1)

Вылить воду из 5-литровой. 

Из 3-литровой перелить остававшуюся воду (1 литр) в 5- литровую. 

Вновь наполнить 3-литровую и эти 3 литра перелить в 5-литровую банку. 1+3=4

В результате проведенных действий в 5-литровой банке будет 4 литра воды.

Answer 2

Problem Analysis

You have two containers, one with a capacity of three liters and another with a capacity of five liters. You need to figure out how to measure four liters of water using these two containers and a tap.

Solution

To measure four liters of water using a three-liter and a five-liter container, you can follow these steps:

1. Fill the five-liter container to its maximum capacity from the tap. 2. Pour the water from the five-liter container into the three-liter container until it is full. This will leave two liters of water in the five-liter container. 3. Empty the three-liter container. 4. Pour the remaining two liters of water from the five-liter container into the three-liter container. 5. Fill the five-liter container to its maximum capacity from the tap again. 6. Pour water from the five-liter container into the three-liter container until it is full. This will leave four liters of water in the five-liter container.

By following these steps, you can measure four liters of water using a three-liter and a five-liter container.

Example

Here's a step-by-step example to illustrate the solution:

1. Fill the five-liter container to its maximum capacity. 2. Pour the water from the five-liter container into the three-liter container. The five-liter container now has two liters of water, and the three-liter container is full. 3. Empty the three-liter container. 4. Pour the two liters of water from the five-liter container into the three-liter container. 5. Fill the five-liter container to its maximum capacity again. 6. Pour one liter of water from the five-liter container into the three-liter container. The three-liter container now has one liter of water, and the five-liter container has four liters of water.

Conclusion

By following the steps outlined above, you can measure four liters of water using a three-liter and a five-liter container.
