A Correct answer
Explanation

Work = Men * Days. 15 * 18 = 12 * D. D = (15 * 18) / 12 = 270 / 12 = 22.5.

AI explanation

Using the formula for man-days, we have 15 men times 18 days equals 270 total man-days required for the work. For 12 men to complete the same task, the required days are 270 man-days divided by 12 men. The result is 22.5 days.
