Answer 2

Problem Analysis

We are given that a store sold 1776 kg of potatoes over three days. On the second day, they sold twice as much as on the first day, and on the third day, they sold three times as much as on the first day. We need to determine how many kilograms of potatoes were sold each day.

Solution

Let's assume that the number of kilograms of potatoes sold on the first day is x kg.

According to the given information: - On the second day, the store sold twice as much as on the first day, so the number of kilograms sold on the second day is 2x kg. - On the third day, the store sold three times as much as on the first day, so the number of kilograms sold on the third day is 3x kg.

The total number of kilograms sold over the three days is 1776 kg. Therefore, we can write the equation:

x + 2x + 3x = 1776

Simplifying the equation:

6x = 1776

Dividing both sides of the equation by 6:

x = 296

So, the store sold 296 kg of potatoes on the first day, 2 * 296 = 592 kg on the second day, and 3 * 296 = 888 kg on the third day.

Answer

The store sold 296 kg of potatoes on the first day, 592 kg on the second day, and 888 kg on the third day.
