The Bronx zoo is going to donate all its insects and fish to other zoos.
Birds raised in wild = 6
Birds raises in captivity = 4
Total reptiles = 5
Total amphibians = 8
Total Mammals = 26
Other animals = 13
Total number of animals in Bronx zoo except insects and fish = 4+5+8+26+13 = 56
% of birds raised in wild to other animals = 6/56*100=10.71( closest option is B)

Consider t as the total number of animals.
If we remove insects and fishes we will leave the zoo with 0.63t animals.
We would then like to know what percentage of these 0.63t are birds raised in the wild.
If birds raised in the wild are 0.06t, then 0.06 x (t) = newper x (0.63t) where newper is the percentage we are asked for.
Thus, newper = 0.06/0.63 = 0.095 ----> Answer is B.
