B)is the right answer
both P and Q can work for 40 days but P and Q works only for 8 days so we can assume that P and Q both work for 4–4 days.
now P leaves Q but the 4 days work has been completed already.
but the statement says that Q required more 48 days to do the work.
so the first 4 days plus the new 48 days gives us 52 days.
if find helpful please mark as brainliest
