Question

СРОЧНО!! ДАЮ 50 БАЛЛОВ!! У двох баках було по 40 л води. Спочатку з першого бака перелили 55% води, яка там була, у другий бак. Потім з другого бака перелили 55% води, яка там виявилася, у перший бак. У якому баку води стало більше та на скільки літрів.

Answer 1

Пошаговое объяснение:

55% = 55 : 100 = 0,55

1) 0,55 * 40 = 22 (л) - воды взяли из 1 бака

2) 40 - 22 = 18 (л) - л воды осталось в 1 баке

3) 40 + 22 = 62 (л) - воды стало во 2 баке

4) 0,55 * 62 = 34,1 (л) - воды взяли из 2 бака

5) 62 - 34,1 = 27,9 (л) - воды стало во 2 баке

6) 18 + 34,1 = 52,1 (л) - воды стало в 1 баке

7) 52,1 - 27,9 = 24,2(л) - воды больше стало в 1 баке

Answer 2

Problem Analysis

We have two tanks, each containing 40 liters of water. We are told that 55% of the water from the first tank is transferred to the second tank, and then 55% of the water from the second tank is transferred back to the first tank. We need to determine which tank has more water after these transfers and by how many liters.

Solution

Let's calculate the amount of water in each tank after the transfers.

1. Transfer from the first tank to the second tank: - 55% of 40 liters = 0.55 * 40 = 22 liters - The second tank now contains 40 + 22 = 62 liters of water.

2. Transfer from the second tank to the first tank: - 55% of 62 liters = 0.55 * 62 = 34.1 liters (rounded to one decimal place) - The first tank now contains 40 + 34.1 = 74.1 liters of water.

Answer

After the transfers, the first tank has 74.1 liters of water, which is 34.1 liters more than the second tank.
