# What is the Weight of Empty Vessel? If

A vessel full of water weighs 40 kg. If it is half filled, its weight is 30 kg. The weight of the empty vessel is.

- 10 kg
- 15 kg
- 20 kg
- 25 kg

**Answer: (3) 20 kg**

**Explanation:-**

The weight of vessel full of water = 40 kg

The weight of vessel half filled of water = 30 kg

Then, the weight of half water of vessel = 40 – 30

= 10 kg

Therefore, the weight of the water of the vessel = 2 x 10

= 20 kg.

Then, the weight of the vessel = 40 – 20

= 20 kg

Hence, the answer is (3) 20 kg.
