Let 1 person do 1 unit of work in 1 day
When 25 people are employed, amount of work in 1 day = 25 units
Amount of work in 16 days = 25*16 = 400
After 16 days, 5 more people are employed and work is completed in 15 days
So work done in next 15 days = 30*15 = 450
If those 5 people are not employed , No. of days needed to complete 450 units of work = 450/25 = 18
But they were supposed to complete the work by 16 days
Hence 2 extra days are needed by 25 people.
When 25 people are employed, amount of work in 1 day = 25 units
Amount of work in 16 days = 25*16 = 400
After 16 days, 5 more people are employed and work is completed in 15 days
So work done in next 15 days = 30*15 = 450
If those 5 people are not employed , No. of days needed to complete 450 units of work = 450/25 = 18
But they were supposed to complete the work by 16 days
Hence 2 extra days are needed by 25 people.

An MNC company employed 25 men to do the official work in 32 days. Aft...
Given:
Number of men = 25
Number of days = 32
Let's assume the total work done by the men in 1 day is x.
So, the total work done in 16 days by 25 men = 16 * 25 * x = 400x
Now, let's find out the remaining work to be done after 16 days.
Total work = 25 * 32 * x = 800x
Remaining work = 800x - 400x = 400x
Now, the additional 5 men were employed for 15 days (from day 17 to day 31)
Total work done by 5 men in 1 day = 5x
So, the total work done by 5 men in 15 days = 15 * 5 * x = 75x
Total work done by 30 men in 15 days = 30 * 15 * x = 450x
Total work done in 31 days = 400x + 450x = 850x
We know that the work was finished one day earlier, which means it was completed in 31 days.
So, the work done in 31 days by 30 men = 850x
Now, let's find out how many days it would have taken if they had not employed additional men.
Let the number of days required be y.
So, the work done by 25 men in y days = 25 * y * x
We know that the work done by 25 men in 32 days = 800x
So, we can write:
25 * y * x = 800x
25y = 800
y = 32
So, if they had not employed additional men, the work would have been completed in 32 days.
Therefore, the additional men helped to complete the work one day earlier.
Hence, the answer is option B, i.e., 2 days.
Number of men = 25
Number of days = 32
Let's assume the total work done by the men in 1 day is x.
So, the total work done in 16 days by 25 men = 16 * 25 * x = 400x
Now, let's find out the remaining work to be done after 16 days.
Total work = 25 * 32 * x = 800x
Remaining work = 800x - 400x = 400x
Now, the additional 5 men were employed for 15 days (from day 17 to day 31)
Total work done by 5 men in 1 day = 5x
So, the total work done by 5 men in 15 days = 15 * 5 * x = 75x
Total work done by 30 men in 15 days = 30 * 15 * x = 450x
Total work done in 31 days = 400x + 450x = 850x
We know that the work was finished one day earlier, which means it was completed in 31 days.
So, the work done in 31 days by 30 men = 850x
Now, let's find out how many days it would have taken if they had not employed additional men.
Let the number of days required be y.
So, the work done by 25 men in y days = 25 * y * x
We know that the work done by 25 men in 32 days = 800x
So, we can write:
25 * y * x = 800x
25y = 800
y = 32
So, if they had not employed additional men, the work would have been completed in 32 days.
Therefore, the additional men helped to complete the work one day earlier.
Hence, the answer is option B, i.e., 2 days.
