12 days. In how many days A alone can do it?​

Answer 1

Answer:

THUS A CAN DO THE WORK IN 30 DAYS.

Step-by-step explanation: Together they can do work in 20 days.

B can do 1/5th of the work in 12 days.

Together's one day work=1/20.

1/5th of the work =1/5×1/20=1/100.

B can do 1/100 work in 12 days,then it"ll do work in 60 days.

B can do the work in 60 days.

Thus,A can do the work in=1/20-1/60=3-1/60=2/60=1/30=1/1/30=30 days.
