Answer»

Answer:

Together they complete the work in 18 days

So, in one day they complete 1/18 work.

Since A is TWICE good as B

So A's WORKDONE in one day= 2x

& B's workdone in one day= x

So, 2x + x = 1/18

3x = 1/18

X = 1/54

So, B's workdone in ONEDAY= 1/54

& A's workdone in one day= 1/27

So, A alone will take 27 days to complete a piece of work

Ans: 27 days
