Simple Practical Answer in a Straight Way guys...

As we know when water freezes, it expands i.e volume increases.

Now take 1000 ml of water in a container.
Take another 100 ml water and freeze it...the volume increases... say.. to 120 ml.

When we submerge the ice in water.

Volume = 1000 + 120 ml.... equilibrium state.
= 1120 ml..........(I)

but after few minutes when ice melts.. its volume decreases.

Volume = 1000 + 100 ml
= 1100 ml..........(II)

Thus the volume decreases. This is when both the combined together and initially Total volume is in water and ice state.

It all depends on assumptions....Interviewer never wants answer only he wants is the way of approach.
