1. Step-by-step explanation:

   In 3 hrs ‘A’ completes 1 piece of work

   => in 1 hr ‘A’ does 1/3 work . . . . . . . .(1)

   In 2 hrs ‘B’ completes 1 piece of work

   => in 1 hr ‘B’ does 1/2 work . . . . . . . .(2)

   So, together A & B complete (1/3 + 1/2) work in 1 hr.

   = 5/6 work in 1 hr

   So, 1 piece of work in 1÷ 5/6 = 6/5 hrs = 1&1/5

   Since 1 hr = 60 minutes

   => 1/5 hr = 60/5 = 12 min

   So together A & B complete the piece of work in 1 hr 12 min
