Answer:
Ram can complete a piece of work in 25 days. In 1 day, R can complete (1/25) of a piece of work.
S can complete a piece of work in 20 days. In 1 day, S can complete (1/20) of a piece of work.
R and S work together for 5 days and complete 5(1/25) + 5(1/20) = (9/20) of a piece of work.
S has to complete (11/20) of the piece of work by himself.
(1/20) of work can be completed in 1 day.
(11/20) of work can be completed in 11 days ie S can complete the piece of work in 11 days.
