Hi could you please help in this DS question - I can;t seem to understand it.

A water container is full. 10% of water evaporate everyday because of heat. If no one has removed from or added to it what will be the ratio of the quantities of water yesterday and today?

I.The ratio of evaporated water to the quantity of water left over after two days is 1:4

II.The quantity of water evaporated in the last two days is 300 gallons.

A) Statement (I) ALONE is sufficient, but statement (II) alone is not sufficient.

B) Statement (II) ALONE is sufficient, but statement (I) alone is not sufficient.

C) BOTH statements TOGETHER are sufficient, but NEITHER statement ALONE is sufficient.

D) Each statement alone is sufficient.

E) Statement (I) and (II) TOGETHER are NOT sufficient to answer the question asked, and additional data are needed
