Answer 2

Problem Statement

You have been given 1260 kg of potatoes in a tent. On the first day, 2/3 of the total potatoes were sold, and on the second day, 5/7 of the remaining potatoes were sold. You need to calculate how many kilograms of potatoes are left after two days of sales.

Solution

To solve this problem, we need to calculate the amount of potatoes sold on each day and subtract it from the initial amount of potatoes.

1. Calculate the amount of potatoes sold on the first day: - The total amount of potatoes is 1260 kg. - 2/3 of the total potatoes were sold on the first day. - To find the amount sold, multiply the total potatoes by 2/3. - Amount sold on the first day = 1260 kg * (2/3) = 840 kg. 2. Calculate the amount of potatoes remaining after the first day: - To find the remaining amount, subtract the amount sold on the first day from the total amount of potatoes. - Amount remaining after the first day = 1260 kg - 840 kg = 420 kg.

3. Calculate the amount of potatoes sold on the second day: - The remaining amount of potatoes after the first day is 420 kg. - 5/7 of the remaining potatoes were sold on the second day. - To find the amount sold, multiply the remaining potatoes by 5/7. - Amount sold on the second day = 420 kg * (5/7) = 300 kg. 4. Calculate the final amount of potatoes remaining after the second day: - To find the final amount, subtract the amount sold on the second day from the remaining amount after the first day. - Amount remaining after the second day = 420 kg - 300 kg = 120 kg.

Therefore, after two days of sales, there are 120 kg of potatoes remaining in the tent.
