Water tanks

A different amount of water is poured into the three identical vessels. The first vessel has 30% water, and the second has 40%. The third container contains 19 liters of water. If we distributed the water from all the vessels equally, the water in each vessel would fill two-fifths of its volume.

What is the volume of one container?

Correct answer:

x =  38 l

Step-by-step explanation:


0.30x + 0.40x+19 = 2/5·3·x

0.30·x + 0.40·x+19 = 2/5·3·x

2.5x = 95


x = 95/2.5 = 38

x = 38
