Diva, the exclamation point represents a factorial. All tha means is you multiply by the next smaller number until you get to 1. 5!= 5 * 4 * 3 * 2 * 1 Make sense? |

Got it. Thanks '91. I haven't taken math in YEARS!

OMG, I remember the first time I saw "!" in math...I was like..OK we've now only moved from the English alphabet to the Greek alphabet...not the math is EMOTIONAL AND yelling at me!!!! |

You said you are a mathie, right 91? What mathematical signs do you have to use to make the following equality possible? 1 1 1 = 6 Did you break out a factorial on me? (1+1+1)!=3!=3*2*1=6? Sure did!! Way to go! |

My cousin sent me this one.
Two stockbrokers, Mr. Greed and Mr. Avarice, hold stocks of Company Gordon and Company Gekko respectively. Both stockbrokers sell their respective stocks of Company Gordon and Company Gekko for $1000 each. Stockbroker Mr. Greed calculates his profit based on cost price while Stockbroker Mr. Avarice calculates his profit based on selling price. While both claim to their clients to have made 25% profit, who is really hoodwinking his client and who has actually made more money for his client?

I don't understand cost price...cost to whom?

Post by Kyng of JDs on Sept 28, 2009 9:16:36 GMT -5
cost to acquire the stock

You wouldn't have a profit at all if the cost to acquire were not less than the selling price so the cost basis would have to give you a larger profit.

This is a question of basis. Figure out what each broker purchased the stock for. As an aside, I have noticed the guy on Mad Money switching between cost and sales to report returns. HIGHLY unethical |

Just intuitively, it seems to me that a 25% profit based on selling price would be more money.

25% of 1000 would be $250 for Mr. Avarice.
Mr. Greed is making 25% profit by selling at $1000. So let x= Cost price
1000-x = .25x
1000= x+ .25x
x = 800
He's making $200, so Mr. Avarice is making more money.

Your assignment is to make a delivery from the depot to your base camp, 1600 miles away. The trip begins normally, but unfortunately, halfway to base camp, your supply truck breaks down. You have no way to call for help. Luckily, in addition to medical supplies, the truck is carrying a Desert Patrol Vehicle (DPV) and two barrels of fuel.
The DPV has a full 10 gallon tank, but to make room for the medical supplies, it can only carry one of the 45 gallon barrels at a time. While you can't transfer fuel between barrels, you can refill the tank from the barrels. Assume the DPV can get 12 miles per gallon, regardless of the load it carries.
How far can you go? Is it far enough to deliver the medical supplies and the DPV to your base camp?

I'm trying to figure out how you can use both barrels of fuel...this seems like a trick question lol. From only one barrel and a full tank, you can go 660 miles (55 gals * 12 miles/gal), and that wouldn't be far enough to make it to the base camp.

I got the same thing and I keep rereading it for the trick..... |

Ok, I don't feel like doing the actual Math right now, but I think its possible to drive some distance, leave that barrel, go back and get the other barrel, and keep repeating this process until you've made it. I'll see if I can figure out the numbers later.

I keep looking at that line "regardless of the load it carries". Maybe there's some way to tow the supply truck with the second barrel in it.

Since that seems to be the strategy, you can figure out the numbers...lol.
