(a) If 9 men can do a piece of work in 28 days, it means that the total man-days required for the work is 9 * 28 = 252 man-days.
To calculate how long it will take 14 men to do the work, we can divide the total man-days by the number of men:
252 man-days / 14 men = 18 days
Therefore, it will take 14 men 18 days to complete the work.
(b) If 9 men can do a piece of work in 28 days, we again have a total of 252 man-days required for the work.
To calculate how many men will be needed to complete the work in 56 days, we can divide the total man-days by the number of days:
252 man-days / 56 days = 4.5 men
Since we cannot have a fraction of a man, we can round up to the nearest whole number.
Therefore, it will take 5 men to complete the work in 56 days.
