Problem Analysis

To solve this problem, we need to find the weight of tomatoes sold in the vegetable kiosk. We are given that 35% of the weight of potatoes is sold, and 20% of the total weight of cucumbers and potatoes is tomatoes.

Solution

Let's calculate the weight of tomatoes sold step by step:

1. Calculate the weight of cucumbers sold: - We are given that 35% of the weight of potatoes is sold. - Therefore, the weight of cucumbers sold is 35% of 800 kg, which is 0.35 * 800 = 280 kg.

2. Calculate the total weight of cucumbers and potatoes: - The weight of cucumbers sold is 280 kg. - The weight of potatoes sold is 800 kg. - Therefore, the total weight of cucumbers and potatoes is 280 kg + 800 kg = 1080 kg.

3. Calculate the weight of tomatoes sold: - We are given that 20% of the total weight of cucumbers and potatoes is tomatoes. - Therefore, the weight of tomatoes sold is 20% of 1080 kg, which is 0.20 * 1080 = 216 kg.

Answer

The vegetable kiosk sells 216 kg of tomatoes.

Verification

Let's verify the answer using the given information:

- The weight of potatoes sold is 800 kg. - The weight of cucumbers sold is 280 kg. - The weight of tomatoes sold is 216 kg.

According to the problem statement, the weight of cucumbers and potatoes should add up to 1080 kg, and the weight of tomatoes should be 20% of 1080 kg. Let's check if these conditions are satisfied:

- The weight of cucumbers and potatoes is 280 kg + 800 kg = 1080 kg. - 20% of 1080 kg is 0.20 * 1080 = 216 kg.

Therefore, the answer is verified to be correct.

Conclusion

The vegetable kiosk sells 216 kg of tomatoes.
