Question

Школьники помогали в уборке моркови и работали 4 дня.В первый день они собрали на 230 кг больше,чем во второй день,и на 150 кг больше,чем в третий день.В третий день они собрали на 259 кг меньше,чем в четвертый.Сколько килограммов моркови собрали школьники за все 4 дня,если в первый день они собрали 650 кг?

Answer 1

650-230=420 кг собрали во второй день
650-150=500 кг собрали в третий день
500+259=759 кг собрали в четвертый день
650+420+500+759=2329 кг собрали за 4 дня

Answer 2

Problem Analysis

We are given information about a group of schoolchildren who helped clean up carrots for 4 days. On the first day, they collected 230 kg more than on the second day, and 150 kg more than on the third day. On the third day, they collected 259 kg less than on the fourth day. We need to determine how many kilograms of carrots the schoolchildren collected in total over the 4 days, given that they collected 650 kg on the first day.

Solution

To solve this problem, we can break it down into smaller steps: 1. Determine the amount of carrots collected on the second day. 2. Determine the amount of carrots collected on the third day. 3. Determine the amount of carrots collected on the fourth day. 4. Calculate the total amount of carrots collected over the 4 days.

Let's calculate each step:

1. Determine the amount of carrots collected on the second day: - We know that on the first day, they collected 230 kg more than on the second day. - Therefore, the amount of carrots collected on the second day is 650 kg (from the first day) minus 230 kg. - The amount of carrots collected on the second day is 420 kg.

2. Determine the amount of carrots collected on the third day: - We know that on the first day, they collected 150 kg more than on the third day. - Therefore, the amount of carrots collected on the third day is 650 kg (from the first day) minus 150 kg. - The amount of carrots collected on the third day is 500 kg.

3. Determine the amount of carrots collected on the fourth day: - We know that on the third day, they collected 259 kg less than on the fourth day. - Therefore, the amount of carrots collected on the fourth day is 500 kg (from the third day) plus 259 kg. - The amount of carrots collected on the fourth day is 759 kg.

4. Calculate the total amount of carrots collected over the 4 days: - To calculate the total, we sum up the amounts collected on each day: 650 kg (first day) + 420 kg (second day) + 500 kg (third day) + 759 kg (fourth day). - The total amount of carrots collected over the 4 days is 2,329 kg.

Therefore, the schoolchildren collected a total of 2,329 kg of carrots over the 4 days.

Answer

The schoolchildren collected a total of 2,329 kg of carrots over the 4 days.
