We have total $100 and we need to buy exactly 100 Birds. The Price list for Birds is as follow:
1) 1 Parrot = $5
2) 1 Crow. = $1
3) 20 Sparrows = $1

BUT CONDITIONS

You have to spend all $100
You have to buy exact 100 Birds
You have to buy all three types of Birds. So you must have all three kind of birds when you finish buying.

$ 20 = 1 sparrow 
$ 80 = 4 sparrows
$ 1 = 1 crow
$ 5 = 1 parrot 
∴ $ 19 = 95 parrots
therefore,  4 + 1 + 95 = 100 birds 
and , $ 80 + $ 1 + $ 19 = $ 100
  i hope it helps ................................^_^
