If 42 men can do a work in 15 days how many men are required to complete it in 21 days?
of men is inversely related to # of days: 42 men * 15 days = x men * 21 days x = (15*42) / 21 = 30 men Answer: 30 men
If it takes 6 men 10 days to do a job how many days will it take 15 men?
Assuming that all the men work at the same rate, when the number of men is multiplied by 15/6, the time required will be divided by 15/6. 10/(15/6) = 4 days.
How many days could 20 men do a piece of work which 25 men can do in 32 days?
25 men in 32 days do 25*32 = 800 man-days of word. If you have 20 men, they would take 800/20 = 40 days.
10 men and 15 women can finish work in 6 days 1 man can finish in 100 days How many days will it take for 1 woman to finish her work?
225 days
If 10 men can finish a work within 5 days how many men will finish within 20 days?
job is 50 man days, so 2½ men in 20 days but you can't get half a man, (unless he only works for 20 half-days), so 3 men for 10 days and 2 men for the other 10.
16 men can do a piece of work in 10 days How many men are needed to complete the work in 40 days?
4 men are required

10 Men can make a wall in 8 days. How many men required to complate the same work in half day?
The Number of men required is 160 Explanation: Let no. of men = m1 = 10 Let no. of days required = d1 = 8 Let no. of men required to finish the work in 1/2 days = m2 Let no of days required for m2 men = 1/2 Now we have to find the no. of men required to complete the work in 1/2 day so the calculation will be, m1d1 = m2d2 (10)(8) = m2(1/2) 80 = m2(1/2) [ By taking the dividend 2 left side it will go into multiple ] 80 x 2 = m2 160 = m2 Therefore, Number of men required to finish the work in 1/2 day is **160 men**
If it takes 6 men 10 days to do a job how many days will it take 15 men?
Assuming that all the men work at the same rate, when the number of men is multiplied by 15/6, the time required will be divided by 15/6. 10/(15/6) = 4 days.

A certain number of men can finish a piece of work in 10 days If however there were 10 men less it will take 10 days more for the work to be finished How many men were there originally?
If a "certain number of men" less 10 takes 20 days (twice as long) to finish the piece of work, then the "certain number of men" who can finish the work in 10 days would 20. If it takes 10 men less twice as long to do the work, then twice 10 men (20) can finish the job in 10 days.
If 3 men or 6 boys can do a piece of work in 20 days then how many days with 6 men and 8 boys take to do the same work?

How many days could 20 men do a piece of work which 25 men can do in 32 days?

If 6 men took 20 days to plow 1 acre of land how many days will 4 men will take to plow 1 acre of land?

How many days are in 7000000 man hours?
That depends on how many men there are. If there is 1 man, then he does 7,000,000 man-hours of work in 7,000,000 hours, or about 798 years of continuous work. If there are 1,000 men, then they do 7,000,000 man-hours of work in 7,000 hours, or about 292 days of continuous work. If there are 100,000 men, then they do 7,000,000 man-hours of work in 70 hours, or about 2.917 days of continuous work. The problem we have with this question is that a "man-hour" is not a unit of time.
If 10 men can finish a work within 5 days how many men will finish within 20 days?
