Question

1 rabbit saw 6 elephants while going to the river. Every elephant saw 2 monkeys going towards the river. Every monkey holds 1 parrot in their hands.
How many Animals are going towards the river???

Answer 1

1+6=7

6*2=12

12*1=12

7+12+12=31

31 animals

Answer 2

So,
from first line it's clear that we have 1 rabbit and 6 elephants going towards the river.

Each elephant saw 2 monkeys,
there are 6 elephants and if they all saw 2 monkeys, then there are 2×6 i.e 12 monkeys.

Each monkey holds 1 parrot, and there are 12 monkeys. Therefore there are 12 parrots.

Add all the numbers of animals (they all belong to animalia kingdom, so I'm gonna count birds as an animal too even though they are practically not)

So,
there are total no. of animal (including aves) going towards the river is, (1 + 6+12 + 12) 31.


But if you're not counting birds as animals then there are (1+6+12) 19 animals going towards the river.
