A school bus travels from Veldhoven to Roosendaal. There are four children in the bus. Each child has four backpacks with him. There are four dogs sitting in each backpack. Every dog has four puppies with her. All these dogs have four legs, with four toes at each leg.
The Question:
What is the total number of toes in the bus?
The total number of toes is 5170.
The puppies: 4children × 4backpacks × 4dogs × 4puppies × 4legs × 4toes = 4096
Plus the dogs: 4children × 4backpacks × 4dogs × 4legs × 4toes = 1024
Plus the children: 4children × 2legs × 5toes = 40
Plus the driver of the school bus: 2legs × 5toes = 10
-------+
This gives the following total number of toes: 5170
