There are 11more animals than birds in a pet shop. If there are as many birds as animals and if there are as many animals as birds the no. of legs is 4/5 of the original. How many birds and animals are there?

• let number of animala be A and birds be B.so first condition we get A=B+11
  (11+B)4+2B=X
  4B+2(B+11)=4X/5
  on solving we get B=11 A=22

• on solving this eq u will get ans
  (11+x)*2+4x=4/5((11+x)4+2x)
  x is d no.of irds and 11+x will be no.of animals

• If there are as many birds as animals and if there are as many animals as birds the no. of legs is 4/5 of the original.
  4B+2(B+11)=4X/5
  6B+22=4X/5....(III)
  
  From (II) and (III) we get,
  6B+22=(4/5)*(6B+44)
  6B=4*44-5*22=66
  B=11
  substituting in eq(I)
  A=22
  
  Hence there is 11 birds and 22 animals.
