animal riddle?

Question

Chickens cost you 50 cents
pigs cost you $2.00
Cows cost you $10.00

you get 100 animals for $100
how many animals do you buy?

Answer 1

The answer is in the question... "you get 100 animals..."

100

If you mean how many of each animal, there are three unknowns and only two equations so you need to solve iteratively or by trial and error.

eq. 1: aC + bP + cW = $100

C=Cost of Chickens, P=Costo of Pigs, W=Cost of Cows
a=# chieckens, b=# pigs, c=# cows

eq. 2: a + b + c = 100

One answer would be if you bought 1 cows so c=1.

That means:

aC + bP + cW= $100
a + b + 1 = 100
a = 99 - b
(99 - b)(.5) + b(2.0) = 100
49.5 - .5b + 2b =100
1.5b = 40.5
b = 27
a = 99 - 27 = 72
c = 1

27 pigs, 72 chickes and 1 cow.

Answer 2

Not a good combination. If you get these animals together, they can unleash new strains of viruses into the environment (like SARS etc). Leave out the pigs.

100 animals for $100 is possible with your numbers: 1 cow, 27 pigs, 72 chickens

1 cow --- 10$
27 pig --- 54 $
72 C --- 36$
100 animals --- 100$

Answer 3

This is a very old riddle. You have the price of the pigs at $2.00, it should be $3.00. no way can this be worked out with the prices you state.
94 chickens at 50 cents each =$47.00
5 cows at $10.00 each = $50.00
1 pig at $3.00
$3.00 + $47.00 + $50.00 = $100.00
94 chickens + 1 pig + 5 cows = 100.

The first and second answers would come out to $105.00
1 cow = $10.00
72 chickens = $41.00
27 pigs = $54.00
$10.00 = $41.00 = $54.00 = $105.00
