D Correct answer
Explanation

Using M1*D1 = M2*D2: 36 * 18 = 27 * D2. D2 = (36 * 18) / 27 = (4 * 18) / 3 = 4 * 6 = 24 days.

AI explanation

Using the formula derived from the inverse proportionality of men and days, Men1 multiplied by Days1 equals Men2 multiplied by Days2. Substituting the given values gives 36 men multiplied by 18 days equals 27 men multiplied by the unknown days. Solving this yields 648 divided by 27, which results in 24 days.
