Let a, b, c, and d stand for the fraction of a project that A, B, C, and D can do within each day, respectively.

I like your answer. It is interesting how in America this problem is solved differently from my home country.
I'm intrigued. How do people from your country solve this problem?

#332256 SteelCo
Posted by BMAD on 17 May 2013  02:38 AM
Steelco has received an order for 100 tons of steel. The order must contain at least 3.5 tons of nickel, at most 3 tons of carbon, and exactly 4 tons of manganese. Steelco receives $20/ton for the order. To fill the order, Steelco can combine four alloys, whose chemical composition and cost is given in the table below:
Alloy (%)
Content 1 2 3 4
Nickel 6 3 2 1
Carbon 3 2 5 6
Manganese 8 3 2 1
Cost/Ton ($) 12 10 8 6
Steelco wants to optimize profit (revenuecosts) obtained from filling the order. How much of each Alloy content type must they produce to achieve optimal profit?

#332253 Solve the cryptogram II

18,8,21,24 22,24 2,1,1,25, 4,17,25 8 3,8,13,13 13,8,21,24; 18,8,21,24 22,24 3,4,9,24,10, 4,17,25, 8 3,8,13,13 25,8,24. 3,12,4,9 4,22 8?
The large punctuation is meant to be maintained when you resolve this cryptogram. The small commas is only meant to separate the numbers they go together as a single word.
Like last time, i don't care if you can translate this cryptogram. I want the correct answer in code.

#332164 Walking man's delight
Posted by BMAD on 15 May 2013  01:29 AM
Enough with traveling salesman who hate long road trips.
Mario Andretti has joined the team, and he loves to drive!
His route today comprises eight towns, placed at the corners of an octagon.
Here are their coordinates:
++++
City x y
++++
1 0 2
2 0 4
3 2 6
4 4 6
5 6 4
6 6 2
7 4 0
8 2 0
++++
The intercity distances, to save some calculations, are NS and EW distances of 6, along with four different diagonal distances of 2.828, 4.472, 5.657 and 6.083
If Mario begins driving at city 1 (coordinates 0 2) and drives until he has visited them all, how far will he be able to drive, and what city will he visit last?
If his objective is to return to his hotel in City 1 after visiting the other cities, how long of a trip could he accomplish?
Are you saying what is the greatest path?

The average hourly wages of men and women in company A are $21 and $16, respectively. The average hourly wages of men and women in company B are $20 and $15, respectively.
If twenty percent of company A employees are men, and forty percent of company B employees are men, which company pays a higher average wage to their employees?

#332149 Falsely accused correctly
Posted by BMAD on 15 May 2013  12:08 AM
Verdict Is Guilty Verdict is not Guilty
Committed Crime 80% 20% False Negative
Innocent of Crime 10% False Positive 90%
The above chart shows the rate that individuals are correctly found guilty or innocent of crimes in a particular jurisdiction.
If 1% of the population of residents in this county were tried in court, what are the chances that someone was correctly charged with crime?

#332115 Death Penalty
Posted by BMAD on 14 May 2013  04:56 PM
You've been sentenced to death in an obscure foreign country which has a strange law. Before the sentence is carried out, two papers  one with "LIFE" written on it and one with "DEATH" written on it  are folded up and placed in a hat. You are permitted to pick out one of the papers (without looking), and if you choose the one with "LIFE" written on it, you are set free. Otherwise, the death sentence is carried out. On this occasion, a meanspirited acquaintance of yours, bent on your demise, has substituted the paper with "LIFE" written on it with another one with "DEATH" written on it. This person gleefully informs you of what he has done and that you are doomed to die. You are not permitted to speak to anyone about this misdeed, nor will you have a chance to switch the papers or the hat yourself in time. How will you avoid certain death?
