Let 'x' be the number of cows, 'y' number of pigs and 'z' number of chicks he bought.
Total number of animals is 100.
x+y+z = 100 ---(1)

Total price is 100
10x+3y+0.50z = 100 ---(2)

2*(2) - (1) gives
19x + 5y = 100
Since x and y are whole numbers
==> x = 5
y = 1

Substituting in (1)
z = 94

5 cows, 1 pig and 94 chicks.
