   Let P takes x days to complete the work
   Then Q takes x/2 days and R takes x/3 days to finish the work
   Amount of work P does in 1 day = 1/x
   Amount of work Q does in 1 day = 2/x
   Amount of work R does in 1 day = 3/x
   Amount of work P,Q and R do in 1 day = 1/x + 2/x + 3/x = 1/x (1 + 2 + 3) = 6/x
   6/x = 2
   => x = 12
   => Q takes 12/2 days = 6 days to complete the work
