100 coins for 100 Parrots
Gondia is a small island and country somewhere. The monetary unit of Gondia is the Parrot. The current coinage of Gondia includes coins of 20, 10, 5, 2.5, 1, 0.5, 0.2 and 0.1 Parrots. How many possibilities do exist to compose a total amount of 100 Parrots using 100 coins but without coins of 1 Parrot? And if not excluding coins of 1 Parrot?

In mathematics, you don't understand things. You just get used to them.
If it ain't broke, fix it until it is.
Always satisfy the Prime Directive of getting the right answer above all else.
