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 42 men can complete a job in 15 days, the total work can be expressed as man-days, which is 42 men × 15 days = 630 man-days. To determine how many men are required to complete the same work in a different number of days, you would divide 630 by the desired number of days. For example, if you want to complete the work in 10 days, you'd need 630 man-days ÷ 10 days = 63 men.
In one day A does 10% of the work and B does 12½%, so after A's 6 days he has done 60%, leaving 40% for B who will need three-and-a-fifth days to complete the work.
1 man would take 80 days to complete the work, so 1 man in 1 day would complete 1/80 of the work. 1 child would take 160 days to complete the work, so 1 child in one day would complete 1/160 of the work. In 1 day, 5 men and 10 children could do 5/80 + 10/160 = 1/16 +1/16 = 1/8 of the work. It would take them 8 days to do the job.
14 days - 4 hrs. Purna.
If a man working 6 hours per day can complete a piece of work in 12 days, the total work done is 6 hours/day × 12 days = 72 hours. To finish the same work in 8 days, he needs to work 72 hours ÷ 8 days = 9 hours per day. Therefore, he must work 9 hours per day to complete the task in 8 days.
4 men are required
If 42 men can complete a job in 15 days, the total work can be expressed as man-days, which is 42 men × 15 days = 630 man-days. To determine how many men are required to complete the same work in a different number of days, you would divide 630 by the desired number of days. For example, if you want to complete the work in 10 days, you'd need 630 man-days ÷ 10 days = 63 men.
2 Days. 2 people x 5 days = 10 days of work. 10 days / 5 people=2 days
In one day A does 10% of the work and B does 12½%, so after A's 6 days he has done 60%, leaving 40% for B who will need three-and-a-fifth days to complete the work.
It might have been possible to answer the question is you had had the time to complete the question!
The term for the goals and tasks of a project, and the work required to complete them, is known as project scope.
1 man would take 80 days to complete the work, so 1 man in 1 day would complete 1/80 of the work. 1 child would take 160 days to complete the work, so 1 child in one day would complete 1/160 of the work. In 1 day, 5 men and 10 children could do 5/80 + 10/160 = 1/16 +1/16 = 1/8 of the work. It would take them 8 days to do the job.

14 days - 4 hrs. Purna.
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 the work that is required is the same amount, then the work to people ratio is 5:20. To get to 1 hour, you need to divide the amount of time by 5. Since you are going to need more people to complete the work, you then multiply the number of people by 5, and 20*5=100. Therefore, you need 100 people to complete the work in 1 hour.
If a man working 6 hours per day can complete a piece of work in 12 days, the total work done is 6 hours/day × 12 days = 72 hours. To finish the same work in 8 days, he needs to work 72 hours ÷ 8 days = 9 hours per day. Therefore, he must work 9 hours per day to complete the task in 8 days.
