Doctor Aibolit distributed 2006 miraculous tablets to four sick animals. The rhinoceros received one more than the crocodile, the hippopotamus received one more than the rhinoceros, and the elephant received one more than the hippopotamus. How many tablets will the elephant have to eat?

#
While the animals haven't eaten the medicine, let's take one pill from the rhinoceros, two from the hippopotamus, and three from the elephant. Now all four have an equal amount. We took 6 pills, so there are 2000 left - 500 for each. We took 3 pills from the elephant, so Aybolit prescribed 503 pills to the elephant.

## Answer

503 pills.
