A Correct answer
Explanation

Using the formula M1*D1/W1 = M2*D2/W2, where W is constant: 5 * 24 = M2 * 15. M2 = 120 / 15 = 8.

AI explanation

Using the formula for work (Men1 x Days1 = Men2 x Days2), we substitute the given values as 5 x 24 = Men2 x 15. Solving for Men2 gives 120 / 15, which equals 8 men.
