Question

a vessel is 1/5th full. if 30litres was added to the vessel it became half full. determine how many more litres needed to be added so that the vessel will be 3/4th full. ​

Answer 1

Answer:

Let the total capacity of the drum be x .

The drum is 2/3 full.

Amount of liquid present in the drum = (2/3)x

It is given that if 50 more litres are added then the drum becomes full.

So the total capacity of the drum = (2/3)x + 50

But the total capacity = x

So, (2/3)x + 50 = x

(2x+150)/3 = x

x = 150

Thus, the total capacity of the drum is 150 litres.
