Answer:

$♡ANSWER♡$

A measured work rate is 1/12 or 4/48 per hour

B measured work rate is 1/16 or 3/48 per hour

Combined measured work rate is 7/48 per hour

The combined work rate for 3 days is 21/48 which leaves a balance of outstanding work at 27/64.

For the remaining balance B will complete alone, So 27 + 3 = 9 hours

Answer: It will take B 9 hours to complete the remaining balance 27/48 of work.
