Problem Analysis

We are given that cucumbers contain 99% water and that 1960 kg of fresh cucumbers were brought to the store. However, due to improper storage, the water content in the cucumbers decreased to 98%. We need to calculate how many kilograms of cucumbers were actually sold.

Solution

To solve this problem, we can use the concept of proportions. The water content in the cucumbers is directly proportional to the weight of the cucumbers. We can set up the following proportion:

99 / 100 = x / 1960

Here, x represents the weight of the cucumbers that were actually sold.

To find the value of x, we can cross-multiply and solve for x:

99 * 1960 = 100 * x

Simplifying the equation:

194040 = 100 * x

Dividing both sides of the equation by 100:

194040 / 100 = x

Calculating the value of x:

x = 1940.4 kg

Therefore, approximately 1940.4 kg of cucumbers were sold.

Answer

Approximately 1940.4 kg of cucumbers were sold.

Explanation

The initial weight of the cucumbers was 1960 kg. However, due to the decrease in water content, the weight of the cucumbers that were actually sold decreased to approximately 1940.4 kg.
