s = 3 c
c = 5 d
s + c + d = 25
3c + c + c/5 = 25
4.2 c = 25
c = 25/4.2 etc

Dragons = X,
Cranes = (X + 5X),
Swans = 3(X + 5X).
X + (X + 5X) + 3(X + 5X) = 25,
X + 6X + 18X = 25,
25X = 25,
X = 25/ 25 = 1 Dragon.
Cranes = 1 + 5*1 = 6.
Swans = 3(1 + 5*1) = 3*6 = 18
Cranes = (X + 5X),
Swans = 3(X + 5X).
X + (X + 5X) + 3(X + 5X) = 25,
X + 6X + 18X = 25,
25X = 25,
X = 25/ 25 = 1 Dragon.
Cranes = 1 + 5*1 = 6.
Swans = 3(1 + 5*1) = 3*6 = 18
