Answer 2

Problem Analysis

We are given that a total of 830 kg of oranges were sold over a period of 3 days. On the second day, 30 kg fewer oranges were sold compared to the first day, and on the third day, the number of oranges sold was three times the number sold on the second day. We need to determine the amount of oranges sold on each day.

Solution

Let's assume the number of oranges sold on the first day is x kg.

According to the given information: - On the second day, 30 kg fewer oranges were sold than on the first day. So, the number of oranges sold on the second day is (x - 30) kg. - On the third day, the number of oranges sold was three times the number sold on the second day. So, the number of oranges sold on the third day is 3 * (x - 30) kg.

The total amount of oranges sold over the 3 days is 830 kg. Therefore, we can write the equation:

x + (x - 30) + 3 * (x - 30) = 830

Simplifying the equation:

x + x - 30 + 3x - 90 = 830 5x - 120 = 830 5x = 950 x = 190

So, the number of oranges sold on the first day is 190 kg.

Using this information, we can calculate the number of oranges sold on each day: - First day: 190 kg - Second day: (190 - 30) = 160 kg - Third day: 3 * (160) = 480 kg

Therefore, the amount of oranges sold on each day is as follows: - First day: 190 kg - Second day: 160 kg - Third day: 480 kg

Answer

The amount of oranges sold on each day is as follows: - First day: 190 kg - Second day: 160 kg - Third day: 480 kg
