Question

На осенней ярмарке 12000 кг картофеля были проданы за 3 дня. За первый день было продано 15% этого количества, а за второй - 45% остатка. Какое количество картофеля было продано за третий день?

Answer 1

За три дня - 12 000 кг
За первый день - 15% от всего
За второй - 45 % от остатка
За третий - ?

1) 12 000 × 0,15 = 1 800 (кг) - в первый день
2) 12 000 - 1 800 = 10 200 (кг)- остаток
3) 10 200 × 0,45 = 4 590 (кг) - во второй день
4) 12 000 - 1 800 - 4 590 = 5 610 (кг) - за 3 день

Ответ: за третий день было продано 5.610 кг картофеля.

Answer 2

Calculation of Potato Sales

To calculate the quantity of potatoes sold on the third day, we need to follow the given information step by step.

1. Total quantity of potatoes at the autumn fair: 12,000 kg.

2. On the first day, 15% of the total quantity was sold. To find this amount, we calculate 15% of 12,000 kg: - 15% of 12,000 kg = 0.15 * 12,000 kg = 1,800 kg.

3. On the second day, 45% of the remaining quantity was sold. To find this amount, we need to subtract the quantity sold on the first day from the total quantity and then calculate 45% of the remaining quantity: - Remaining quantity after the first day: 12,000 kg - 1,800 kg = 10,200 kg. - 45% of 10,200 kg = 0.45 * 10,200 kg = 4,590 kg.

4. To find the quantity of potatoes sold on the third day, we need to subtract the quantities sold on the first and second days from the total quantity: - Quantity sold on the third day = Total quantity - Quantity sold on the first day - Quantity sold on the second day. - Quantity sold on the third day = 12,000 kg - 1,800 kg - 4,590 kg = 5,610 kg.

Therefore, 5,610 kg of potatoes were sold on the third day.
