D Correct answer
Explanation

Using the formula M1*D1*H1 = M2*D2*H2: 10 * 24 * 8 = M2 * 16 * 10. Simplifying: 1920 = 160 * M2. M2 = 1920 / 160 = 12.

AI explanation

Using the constant work formula M1 x D1 x H1 = M2 x D2 x H2, we substitute the given values. 10 x 24 x 8 = M2 x 16 x 10. 1920 = 160 x M2. Solving for M2 gives 12. The required number of men is 12.
