Question

Danny poured 78 liters of water into x,y,and z. The ratio of the volume of water in container x to the volume of water in container y is 5:2. The ratio of the volume of water in container y to the volume of water in container z is 8:11. How much water was poured in container x? How much more water was poured into container x than container z?

Answer 1

x+y+z = 78

x/y = 5/2

y/z = 8/11

(x,y,z) = (40,16,22)

x-z = 18
