Answer 2

Ответ: 840 кг

Пошаговое объяснение:

В первый день продали $\frac{2}{5}$ · 2400 кг = 960 кг

Во второй день продали $\frac{1}{4}$ · 2400 кг = 600 кг

В третий день - х кг.

960 + 600 + х = 2400

х = 2400 - 960 - 600

х = 840 кг

Answer 3

Calculation of Sugar Sold on the First and Second Days

To calculate the amount of sugar sold on the third day, we first need to determine the amount of sugar sold on the first and second days.

According to the information provided, the store sold 2/5 of the total amount of sugar on the first day and 1/4 of the total amount on the second day.

Let's calculate the amount of sugar sold on the first day: - Total amount of sugar = 2400 kg - Amount of sugar sold on the first day = (2/5) * 2400 kg

To find the amount of sugar sold on the second day, we need to subtract the amount sold on the first day from the total amount of sugar: - Amount of sugar sold on the second day = (1/4) * (2400 kg - amount sold on the first day)

Let's calculate the amounts:

Amount of sugar sold on the first day: ``` (2/5) * 2400 kg = 960 kg ```

Amount of sugar sold on the second day: ``` (1/4) * (2400 kg - 960 kg) = (1/4) * 1440 kg = 360 kg ```

Calculation of Sugar Sold on the Third Day

To find the amount of sugar sold on the third day, we need to subtract the amounts sold on the first and second days from the total amount of sugar.

Let's calculate the amount of sugar sold on the third day:

Amount of sugar sold on the third day = Total amount of sugar - Amount sold on the first day - Amount sold on the second day

Amount of sugar sold on the third day = 2400 kg - 960 kg - 360 kg

Calculating the above expression:

Amount of sugar sold on the third day = 1080 kg

Therefore, the store sold 1080 kg of sugar on the third day.
