Given:
- Aakash bought vegetables weighing 10 kg.
- Out of this, 3 kg 500 grams is onions.
- 2 kg 75 grams is tomatoes.
- The rest is potatoes.

To Find:
- The weight of the potatoes.

Solution:

To find the weight of the potatoes, we can subtract the weights of onions and tomatoes from the total weight of the vegetables.

Step 1: Convert the weight of onions and tomatoes to the same unit.

- 3 kg 500 grams = 3.5 kg (since 1 kg = 1000 grams)
- 2 kg 75 grams = 2.075 kg

Step 2: Subtract the weights of onions and tomatoes from the total weight of the vegetables.

Total weight of vegetables = 10 kg
Weight of onions = 3.5 kg
Weight of tomatoes = 2.075 kg

Weight of potatoes = Total weight of vegetables - Weight of onions - Weight of tomatoes

Weight of potatoes = 10 kg - 3.5 kg - 2.075 kg

Weight of potatoes = 4.425 kg

Therefore, the weight of the potatoes is 4.425 kg.

Explanation:

- The given problem states that Aakash bought vegetables weighing 10 kg.
- It is further mentioned that out of this, 3 kg 500 grams is onions and 2 kg 75 grams is tomatoes.
- To find the weight of the potatoes, we need to subtract the weights of onions and tomatoes from the total weight of the vegetables.
- The weight of onions is 3.5 kg (converted from 3 kg 500 grams) and the weight of tomatoes is 2.075 kg (converted from 2 kg 75 grams).
- By subtracting the weights of onions and tomatoes from the total weight of the vegetables, we get the weight of the potatoes, which is 4.425 kg.

4.425 is the correct answer or not
