1 rs=20 sparrow
1 rs=1 peacock
5 rs=1 crow
total rs =100,total count of birds =100
condition:must 3 birds should be selected?

• Number of Sparrows=80, Peacock=1 & Crow=19
  
  Price(in Rs.) of 1 sparrow=1/20, 1 peacock=1 , 1 crow=5 and if number of sparrows=s, peacock=p & crow=c respectively, then s + p + c =100 ----(i) &
  (s/20) + p + 5c =100 ---(ii)
  From (i), p=100-s-c and substituting in (ii), we get (s/20)+100-s-c+5c=100 or c=19s/80
  For s=80, c=19 so p=1
