Explanation

Using the work-man-day formula (M1*D1 = M2*D2), 6 * 20 = M2 * 15. M2 = 120 / 15 = 8.

AI explanation

Using the formula that men and days are inversely proportional, the total work is 6 men multiplied by 20 days, which equals 120 units. To finish this work in 15 days, the required men are 120 divided by 15. The result is 8 men.
