Answer :
Assuming that all the animals are dogs, the number of legs there are would be 240.
60*4=240 legs
240-148=92 legs
All the 92 legs belong to the chickens, so there are 46 chickens.
Since there are 46 chickens,
60-46=14 dogs
60*4=240 legs
240-148=92 legs
All the 92 legs belong to the chickens, so there are 46 chickens.
Since there are 46 chickens,
60-46=14 dogs
