20 men can complete the work in 48 days.

⇒ Total man-days needed for the project = 20 x 48 = 960


8 days of work = 8 x 20 = 160 man-days

⇒ Number of man-days needed to complete the project = 960 - 160 = 800


After 12 more men joined in

⇒ there are 20 + 12 = 32 men


Number of days needed = 800 ÷ 32 = 25 days.


Total number of days needed to complete the job = 8 + 25 = 33 days


Answer: 33 days
