Good morning to all those of you who had a lie in; I have been up trying to install Office 2007 on all the computers, so all I have to do is find where the heck all my old files have gone.
Hold up! What the hell has been going on? The PM box is full to overflowing; I don't have time just now, but will get round later, after I sort the other problem out.
Mark:
WORKERS
4*10 = 3*(10+N)
N = 40/3 - 10
hire 4 workers and finish a bit early
That looks too neat to be true; let me check:
10 workers can do a job in 5 working days,
=> 1 worker does (1/10)/5 = 1/50 of the job per day.
1/50 * 10 * 1 = 1/5 (job completed on 1st day)
1- 1/5 = 4/5 (job left)
1/50 * 3 * (x+10) = 4/5
(3x+30)/50 = 4/5
multiply by 50 on both sides,
3x + 30 = 40
x = 10/3 = 3.33....
So the management should hire at least 4 more workers to complete the job. So Mark was right all along.
TTH: DKI = mixed up kid
Say no more.
