If one pound can feed either 5 chickens or 2 pigs, then ten pounds of grain can feed 20 chickens and how many pigs?
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

This phrase ". . . one pound can feed either 5 chickens or 2 pigs" means that 

   1 chicken eats  = 0.2 pound of grain,  or
   1 pig     eats  = 0.5 pound of grain.

Then 20 chickens will eat 0.2*20 = 4 pounds of grain, and still 10 - 4 = 6 pounds of grain will remain.

It is enough to feed  = 12 pigs.

Answer. ". . . and how many pigs?" - 12 pigs.
