In a small catchment the annual rainfall is given as 750mm/yr,the runoff is 50mm/yr and the infiltration is 70mm/yr.What is the actual evaporation from this catchment?

Why don't you think that the answer to the question as stated is 630mm/yr ?

What other information is given?

If these figures are realistic, then, paying more attention to retaining water must be a subject worth studying. I admit I've never really thought about it.

Where does it say that catchment starts dry, or how much water is there to start, and how much water is left after a year? Do we assume the catchment starts dry and ends dry? Why? Is the catchment in sunlight? Protected from the wind? Temperature range? What's the altitude (atmospheric pressure)? It's like sayng How long will it take me to cross the ocean??

I was assuming a "steady state" situation.
