You have 5 days.
You have 20 pigs.
You must kill some pigs every day. All pigs should be slaughtered at the fifth day. :eek:
The Number of pigs killed per day must be odd.
Write it like this:
7,1,5,3,1

I'm sorry; I missed the part where there was a question or, since this is the contest board, a challenge.
Write the day and how many pigs you killed. Write all the kills in five days.
Your goal is to kill all the pigs. But only killing odd number of pigs.
I don't think this is even possible. If you add an odd number of odd numbers, isn't the result always an odd number? (eg, 1+1+1=3, 3+5+1 = 9, 3+7+9+1+1=21)
There's probably a way to prove it, but I've never been one for proofs...
I don't know if it's possible, my friend told me this.
I'l have to beat him up if i prove this is immposible.
Yes, you are correct. If you add an even number of odd numbers together, you always get an even number. Adding an odd number to that (or any other) even number yields an odd number.Quote:
