Explanation

Work = Men * Days. 15 * 16 = 240 man-days. 240 / 24 = 10 days.

AI explanation

Using the work equivalence formula, 15 men multiplied by 16 days equals 24 men multiplied by the required days. This gives a total of 240 man-days. Dividing 240 man-days by 24 men results in 10 days to complete the work.
