- First, calculate the work rate for 16 men painting 15 walls in 45 days.

- Total work = 15 walls; Total man-days = 16 men × 45 days = 720 man-days.

- Work rate = 720 man-days / 15 walls = 48 man-days per wall.

- Now, find out the time taken by 20 men to paint 20 walls.

- Total work for 20 walls = 20 walls × 48 man-days/wall = 960 man-days.

- Days required = Total man-days / Number of men = 960 man-days / 20 men = 48 days.

- Option 3: 48 is the correct answer.
