2. (i) If a pipe can fill a tank in x hours, then : part
filled in 1 hour = 1/x

(ii)

*If a pipe can empty a full tank in**y*hours, then : part emptied in 1 hour = 1/y
(iii) If a pipe can .fill a tank in x hours and
another pipe can empty the full tank in y hours (where

*y> x),*then on opening both the pipes, the net part filled in 1 hour = (1/x)-(1/y)
(iv)

*If a pipe can fill a tank in x hours and another pipe can empty the full tank in y hours (where x >**y),*then on opening both the pipes, the net part emptied in 1 hour = (1/y)-(1/x)
