Problem Analysis

We are given that a store sold onions and potatoes, with the quantity of potatoes being twice that of onions. The total weight of the items sold was 387 kg. We need to determine the weight of onions and potatoes sold on that day, as well as the difference in weight between the two.

Solution

Let's assume the weight of onions sold is x kg. Since the weight of potatoes is twice that of onions, the weight of potatoes sold would be 2x kg.

According to the given information, the total weight of onions and potatoes sold is 387 kg. Therefore, we can write the equation:

x + 2x = 387

Simplifying the equation:

3x = 387

Dividing both sides by 3:

x = 387 / 3

Calculating the value of x:

x = 129 kg

Therefore, the weight of onions sold is 129 kg, and the weight of potatoes sold is twice that, which is 2 * 129 = 258 kg.

To find the difference in weight between the two, we subtract the weight of onions from the weight of potatoes:

258 kg - 129 kg = 129 kg

So, the weight of potatoes sold is 129 kg more than the weight of onions sold.

Answer

On that day, the store sold 129 kg of onions and 258 kg of potatoes. The weight of potatoes sold was 129 kg more than the weight of onions sold.
