A Correct answer
Explanation

Work is constant. M1 * D1 = M2 * D2. 35 * 15 = M2 * 25. M2 = (35 * 15) / 25 = 35 * 0.6 = 21.

AI explanation

Using the formula M1 x D1 = M2 x D2, we calculate the required women as 35 x 15 = 25 x M2. Solving this gives M2 = 525 divided by 25, which equals 21. Therefore, 21 women are required to do the work in 25 days.
