Question

A water tank is half full of water. After 600L of water is used, the water tank is now found to be onethird
full. How much does the water tank hold when it is full?

Answer 1

capacity of water tank = x L

 

now it hold x/2 L

 

x/2 -600 =(1/3)x

 

x/2 -600 =x/3

x/2 -x/3 =600

 

3x -2x =3600

 

x =3600 L
