please check the numerical values in the question again......and the answer, may be a typo somwher.......
the logic is

Net Fluid Movement = Fluid movemnt out of capillary - into the capillary

Here the value of end arterial capillary hydostatic pr is given jus to confuse , in reality arterial pr had hardly any effect on capillary pr .its the venous pr that determines capillary b.p.

please confirm the answer as requested by others earlier

also do correct me am i wrong (it pricks real bad so say this again and again )
