Give the step-by-step reasoning process and then the final answer. In a Zoo, there are different animals. There are 5 giraffes and twice as many penguins. Penguins make up 20% of all the animals in the Zoo. How many elephants are there in the Zoo if they make up 4% of all the animals?

There are twice as many penguins as giraffes, so there are 5 * 2 = 10 penguins. The penguins make up 20% of all animals, so there are 100 / 20 * 10 = 50 animals in the whole Zoo. 4% of animals are elephants, so there are 4 / 100 * 50 = 2 elephants at the Zoo.
The final answer: 2.
