Answer 1

✨ Hey_Mate✨

A can do a piece of work = 20days

     One day work of A = 1/20

     B can do the same work = 30 days

     One day work of B = 1/30

    One day work of A and B = 1/20 + 1/30

                                               = 5/60

    No. of days need to complete the work of A and B = 1/One day work of A and B

                                                                                         = 1/5/60

                                                                                         = 1/5×60  

                                                                                         = 12 days.
