Question

Анвару воды в бурдюке хватает на 14 дней,а с братом на двоих 10 дней. на сколько дней хватит воды в том же бурдюке брату Анвара?

Answer 1

Вся вода - 1
1/14 воды в день Анвар
1/10 воды в день на двоих
1/10-1/14=7/70-5/70=2/70=1/35
1:1/35=35 дней хватит брату

Answer 2

Пусть  брату Анвара воды хватает на х дней, тогда за 1 день он выпивает 1/х часть бурдюка, а Анвар - 1/14. Вместе они выпивают бурдюк за 10 дней, то есть 1/10  часть бурдюка в день. Получим уравнение:1/х+1/14=1/10;
1/х=1/10-1/14=1/35
1/х=1/35
х=35
Ответ: на 35 дней

Answer 3

Calculation of Water Supply

To calculate how many days the water supply in the same jug will last for Anvar's brother, we need to determine the daily water consumption for both Anvar and his brother.

According to the information provided, the water supply in the jug is sufficient for Anvar for 14 days and for both Anvar and his brother for 10 days.

Let's assume that Anvar's daily water consumption is represented by A and his brother's daily water consumption is represented by B.

Based on the given information, we can set up the following equations:

- For Anvar: A x 14 = Water Supply - For Anvar and his brother: (A + B) x 10 = Water Supply

To find the value of B, we can rearrange the second equation as follows:

B = (Water Supply / 10) - A

Now, let's substitute the value of A from the first equation into the second equation:

B = (Water Supply / 10) - (Water Supply / 14)

Simplifying the equation:

B = (Water Supply x (14 - 10)) / (10 x 14)

Now, we can calculate the value of B using the given information.

Calculation

Since we don't have the exact value of the water supply in the jug, we cannot provide an exact answer. However, we can calculate the value of B using the given information.

Let's assume the water supply in the jug is represented by W.

B = (W x (14 - 10)) / (10 x 14)

Simplifying the equation:

B = (W x 4) / 140

Therefore, the water supply in the same jug for Anvar's brother can be calculated using the above equation.

Please provide the value of the water supply in the jug, and I will be happy to calculate the number of days it will last for Anvar's brother.
