@ nadeem5476! You are checking our IQ level hain na
well let me guess... say if you know that your car's radiator has a capacity of 3L... now 60% of 3L would be like 1.8L.
In case you dont know the exact capacity of the radiator... drain out the water... add water this time using a bottle (e.g. 0.5, 1 or 1.5L bottle)... now you will know how much is the capacity.
