I am of level 6. My question is :
80 sparrows are of 1 SR, 1 parrot is of 5 SR and 1 pegion is of 1SR.A person have to buy 100 birds of 100 SR. How many sparrows,pigeons and parrots would he buy?(He have to buy every type of bird).

Air has answered it by observation.
Which we can validate by a technical discussion
Technical Method
I dont like pigeons, lets keep crows instead of them
Naming
sparrows = S
parrots = P
crows = C
In terms of sparrows, lets count the worth of remaining things,
1 P = 400 S
1 C = 80 S
100 SR = 8000 S
So we get two equations
a(400) + b(80) + c = 8000
a+b+c = 100.
So,
a(399) + b(79) = 7900
So solve this diophantine equation to get (a,b) = (0,100).
