Forty eight men working at the rate of eight hours a day can build a wall of 250 m length in 25 day. all the man started the work and after 10 days eight men left. Now instead of 250 m long wall, 300 m long wall is to be constructed how many hours a day they have to work so that the remaining work is completed in 16 more days?

Forty eight men working at the rate of eight hours a day can build a wall of 250 m length in 25 day. all the man started the work and after 10 days eight men left. Now instead of 250 m long wall, 300 m long wall is to be constructed how many hours a day they have to work so that the remaining work is completed in 16 more days? Correct Answer 12 hours

Concept:

M1D1H1/W1 = M2D2H2/W2

Calculation:

⇒ (48 × 25 × 8)/250 = (48 × 10 × 8 + 40 × 16 × H)/300

⇒ H = 12 hours

∴ The required result will be 12 hours.

Paddy transplantation in Punjab is a very hard labor-intensive back-breaking job. In the transplant season, teams of special people swarm the entire rural landscape employed by the farmers and can be seen laboring away in the fields under the hot sweltering sun. Farmer Jagtar Singh has a full-time help at his sprawling farm who goes by the name of Hari, and who hails from Allahabad, UP. During the paddy transplant season, it is up to Hari to rope in his brothers, sons, and cousins from his native village to complete the task well in time. All his people are skillful and masters of the trade and equally efficient at their jobs. So, this past season, this is how the work went. Hari started the work and after 't' hours was joined in by his brother Jaggi. After another 't' hours, Neelu, their cousin, also jumped into the fray. So, after every 't' hours, 1 person kept on joining the team of already working men, and this process kept on continuing till the completion of the work. The last person worked for 't' hours. In the last season, the very same men had completed the same work working 2 shifts of 12 hours all of them working simultaneously owing to some peculiar weather conditions and time constraints. Jagtar Singh is a fair and just paymaster which is why he faces no labor shortage at this crucial time and which is why the whole 'Hari clan' are more than happy to work for him and are at his beck and call. He pays each of them individually proportional to the work done by them. This time around, Hari received 11 times as much as Surinder, his eldest son, who was the last person to join in. In how much time was the work completed?
Newton, Einstein, and Tesla working alone can do a piece of work in 20, 30, and 60 days respectively. All three of them start the work together, but after x days Newton leaves and then after y more days Einstein leaves and Tesla completes the remaining work. If Einstein had not left, Tesla and Einstein would have completed the remaining work in (y + 6) days after Newton had left. If both Newton and Einstein had stayed, the work would have been completed in (x + 6) days. What is the total number of days taken to complete the work?

In the following question, two statements are numbered as A and B. On solving these statements, we get quantities A and B respectively. Solve both quantities and choose the correct option. Quantity A: Twelve persons can construct a 320 m long wall in 32 days working 8 hours a day. In how many days can 40 persons construct a 250 m long wall working 10 hours a day? Quantity B: A can finish the work in 15 days and B in 30 days. They both work together for 5 days and then B leaves. How many days will A take to complete the remaining work?
A, B, and C can do a piece of work in 24 days, 30 days, and 40 days respectively. They start to work together and after four days, 50% of the completed work is destroyed by the air thereafter, they work for 6 days and after that, 16.66% of the total completed work is destroyed by rain. Thereafter, B left the work and A, C worked with twice their efficiency, after how many days remaining work was completed by A and C.
Two men and women are entrusted with a task. The second man needs three hours more to cope up with the job than the second man and the woman would need working together. The first man, working alone, would need as much time as second man and the woman working together.
