• x/20+y+5z=100
  x+y+z=100
  eliminating y from above eqn and evaluting for z/x we get 19/100,as we know z&x should be integer so ans ans is 80 sparrow,19 parrot,1 crow.

• let sparrows be a, crows be b, parrots be c then...
  a/20 + b/1 + 5c=100

  let c be 7,b be 5 , a be 1200
  or a,b,c =1000,5,9
  or 600,25,9
