Answer:
16 animals
Explanation:
It's a step by step approach.
Every monkey had one tortoise in hand.
There was 3 monkeys.
So 3 monkeys had one tortoise making it 3 tortoise.
Since the elephants are all going towards the same River it's definitely that the monkey they all saw is the same 3 set of monkeys.
Then a rabbit .
Total animal = 1 rabbit + 3 monkeys + 3 tortoise + 9 elephants
Total animal= 16 animals
