7-53) Answer
150
Solution: The ratio of chickens
versus the total number of animals is 1/(4+1) = 1/5.
The ratio of turkeys versus the total number of animals is 2/(13+2) = 2/15.
The ratio of rabbits versus the total number of animals is 4/(11+4) = 4/15.
The ratio of the sum of chickens, turkeys and rabbits versus the total number of
animals is 1/5 + 2/15 + 4/15 = 9/15.
Therefore, the ratio of pigs versus the total number of animals = 6/15 i.e. 2/5.
Therefore, the total number of animals is 60 * (5/2) = 150 animals
