If iI go to work at 9:30 and get off at 6:00 how many hours a day do I work?
without and lunch break you would be working 8.5 hours....obviously subtract any time that you spend off the clock for lunch. A half hour lunch would bring you down to 8 hours even while an hour lunch would drop you to 7.5
If 25 men working 6 hours a day, can do a job in 8 days, how many hours a day must 24 men work in order to finish the job in 10 days?
No of man-hours required to complete a piece of work = 25 x 6 x 8 = 1 200No of man-hours required by 24 men = 24 x h x 10Equating: 25 x 6 x 8 = 24 x h x 10Time needed per day h = 1 200/(24 x 10) = 5 hours
If 9 men working 6 hours a day can do work in 88 days, then 6 men working 8 hours a day can do it in how many days?
Hope you understand..
If 5 men work 6 hours per day, they complete the work in 16 days. In how many days will 10 men complete the same work by working 8 hours a day?
We will use Chain Rule to solve this question.According to Chain Rule, the work efficiency remains constant.[math]\dfrac {W}{WF \times T} [/math]= ConstantHere W = Work Done, WF = Workforce, T = Time.Let the number of days needed be 'x'.Applying Chain Rule,[math]\dfrac {W}{5 \times 6 \times 16} = \dfrac {W}{10 \times 8 \times x} [/math]Or, [math]\fbox {x = 6 Days}[/math] (Answer)
25 men can do a work in 6 days working 8 hours a day. How many hours a day must 30 men have to work in order to finish a work twice as great in 8 days?
If the number of men is changed n times, the time will change by (1/n) times the initial time.It is stated that 25 n is 30.1/n = 25/30Initial time is 6*8 =48 hours.(1/n) of 48 is (25/30) of 48 = 40 hours for one job.For 2 such jobs , time needed is 80 hours80 hours in 8 days means 10 hour per day.
A man works 8 hours daily, and finish his work in 12 days. If he works 6 hours, in how many days would he complete his work?
Total hours = 12x8 =96If he do work 6 hours dailyThen total hours divided by 6I.e 96/6= 16 daysIn 16 days he will complete his work
If 9 men take 12 days, working 5 hours a day, to build a bridge, how many days will 30 men take working 6 hours a day?
Given scenario:5 hrs x 12 (days) x 9 (men) = 540 hrs total to complete the bridgeProblem:The bridge takes 540 hrs to be built so you get the following equation -6 hrs x __ (days) x 30 (men) = 540 hrsDivide both sides by 6 then 30 to get__ (days) = 3So it will take 3 days for the bridge to be built**DISCLAIMER: I didn’t show how the units cancel out but…it works**
