Question

В магазин завезли 324 кг мандарин. в первый день продали 2/9 всех мандарин, а во второй день продали 4/9 остатка. в третий день продали 5/12 тех мандарин, некоторые были проданы за первые два дня. Сколько килограмм мандарин осталось в магазине после трёх дней? Помогите пожалуйста, очень надо

Answer 1

324:9*2=72 кг продали в 1 день
324-72=252 кг осталось
252:9*4=112 кг  продали во 2 день
72+112=184 продали за 2 дня
184:12*5=76,7 кг продали в 3 день
324-(72+112+76,7) = 63,3 кг осталось после трех дней

Answer 2

Calculation of Mandarin Sales

To calculate the remaining kilograms of mandarins in the store after three days, we need to determine the amount sold each day and subtract it from the initial quantity of 324 kg.

1. First Day Sales: - 2/9 of all mandarins were sold. - Calculation: (2/9) * 324 kg = 72 kg.

2. Second Day Sales: - 4/9 of the remaining mandarins were sold. - Calculation: (4/9) * (324 kg - 72 kg) = 144 kg.

3. Third Day Sales: - 5/12 of the remaining mandarins were sold. - Calculation: (5/12) * (324 kg - 72 kg - 144 kg) = 45 kg.

Calculation of Remaining Mandarins

To find the remaining kilograms of mandarins in the store after three days, we subtract the total sales from the initial quantity of 324 kg.

- Total Sales: 72 kg (first day) + 144 kg (second day) + 45 kg (third day) = 261 kg.

Therefore, the remaining kilograms of mandarins in the store after three days is:

- Remaining Mandarins: 324 kg - 261 kg = 63 kg.
