10 men can complete a work in 8 days and 10 children take 16 days to complete the same workhow many days will 5 men and 10 children Wiil take 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.

If 20 people complete a work in 5 houshow many people are required to complete that work in 1 hour?

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.

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**
