Problem solved.Wiping out profits when he rebuys it has nothing to do with it
say he starts with $100
$100-5=95 when he originally buys
95+7=102 when he sells for profit
102-9=93 when he rebuys
93+12=105 when he sells again
theres no arguing with that
Hopefully all you people saying $3 are saying that because you think it's a trick. You guys didn't actually come up with $3 legitimately, did you?
"A person bought a chicken for 5 dollars and sold it later for 7 dollars. He then felt he could do better, so he bought it back for 9 dollars and sold it to another person for 12 dollars. How much money did he make?"
OK say I have 10 $1 bills in my pocket:
xxxxxxxxxx
I buy a stupid chicken for $5. Here's my wallet now:
xxxxx
I sell it for $7:
xxxxxxxxxxxx
I buy it for $9:
xxx (yes, now I'm down $2 from where I was after I originally bought it. but who cares...I'll make it up in the resale)
I sell the chicken for $12:
xxxxxxxxxxxxxxx
Count the final number of bills (x's), and you get 15...which just so happens to be 5 more than I started with
What if you have zero dollars and are borrowing the money...
You borrow 5 , sell for 7 , so you are at +2 after paying back the 5.
You borrow 7 more to buy it back @ 9 dollars, resell for 12, after paying back the new loan of 7 you have 5 profit.
Was surfing another forum and find it funny that many people who claimed to be scientist or engineer got this question wrong, this type of questions are type of sample math questions that could be found in third grade elementary math class in Chinese schools...
Anyway, let see how many "smart" people are here in the RX since we're always dealing with math and stats...
