O 28days
21 days
024days
O 36days​

Answer 1

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

Answer 2

Answer:

27 days

Step-by-step explanation:

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
