Let the tank has total capacity of x liters
When ¹/₃ is full it means to say that it has ˣ/₃ litres of water

Now when 100 litres water was added it became half full

Note:-  half full = ˣ/₂ litres and 100 litres water was added to it = ˣ/₃ +100 litres

∴  \frac{x}{2} = 100+ \frac{x}{3}

 \frac{x}{2} -  \frac{x}{3} =100
 \frac{x}{6} = 100
x=600

Therefore the tank can hold 600 litres of water...
