A vessel full of water weighs 40 kgs. If it is half filled its weight is 30 kgs. Find the weight of the empty vessel.

Let the weight of empty vessel be x and weight of water be y.


The weight of vessel fully filled with water = 40


X + y = 40 …….(i)


The weight of vessel half filled with water = 30


X + y/2 = 30 ……(ii)


Eq(i) – eq(ii) = y/2 = 10


Y = 20 kg


Total weight of water in the vessel = 20 kg.


Weight of empty vessel = 40 – 20


Weight of empty vessel = 20 kg.


Given, Weight of Full vessel = 40 kg
