Answer»

If A takes x DAYS to do a work then B takes 2X days to do the same work

= > 1/x+1/2x = 1/18

= > 3/2x = 1/18

= > x = 27 days.

HENCE, A alone can finish the work in 27 days.

If A takes x days to do a work then B takes 2x days to do the same work

= > 1/x+1/2x = 1/18

= > 3/2x = 1/18

= > x = 27 days.

Hence, A alone can finish the work in 27 days.
