Question

В понедельник на склад магазина привезли яблоки и груши, упакованные в ящики. Яблок было 75%. Во вторник довезли еще груши, после чего яблок стало 25%. А в среду привезли яблок, и их снова стало 75%. Во сколько раз увеличилось суммарное количество яблок и груш за эти 3 дня?

Answer 1

Ответ:на 100% или в 2 раза

Пошаговое объяснение:

Вторник довезли 50% груш

Среда довезли 50% яблок

50%+50%=100%

Answer 2

Calculation of the Total Quantity of Apples and Pears

To calculate the total quantity of apples and pears over the course of three days, let's break down the information provided:

- On Monday, apples and pears were delivered to the store in boxes. The apples accounted for 75% of the total quantity. - On Tuesday, additional pears were delivered, after which the percentage of apples decreased to 25%. - On Wednesday, more apples were delivered, and the percentage increased back to 75%.

To determine the increase in the total quantity of apples and pears, we need to establish a baseline. Let's assume that the initial total quantity of apples and pears was 100 units.

1. Monday: - Apples: 75% of 100 units = 75 apples - Pears: 25% of 100 units = 25 pears

2. Tuesday: - Additional pears were delivered, but the total quantity remains the same (100 units). - Since the percentage of apples decreased to 25%, the number of apples must have decreased as well. - Let's assume the number of apples decreased by x units. - Therefore, the number of pears must have increased by x units.

- New number of apples: 75 - x - New number of pears: 25 + x

3. Wednesday: - Additional apples were delivered, bringing the percentage back to 75%. - The total quantity remains the same (100 units). - Let's assume the number of apples increased by y units. - Therefore, the number of pears must have decreased by y units.

- New number of apples: 75 - x + y - New number of pears: 25 + x - y

To find the values of x and y, we can set up two equations based on the given information:

Equation 1: (75 - x) / 100 = 25 / 100 Equation 2: (75 - x + y) / 100 = 75 / 100

Solving these equations will give us the values of x and y, which will allow us to calculate the final quantities of apples and pears.

Please wait a moment while I solve the equations.
