Can you solve these mental workouts? Some need lateral thinking - solving problems by an indirect and creative approach, typically through viewing the problem in a new and unusual light.
How many penguins will an average polar bear eat in any given month.
Assume that penguins live with a density of 1,000 penguins per square mile and can run at an average speed of 7 miles per hour on land and swim at 20 miles per hour.
Also assume that a polar bear has a territory of 10 square miles, can run at 25 miles per hour and swim at 10 miles per hour,
A polar bear could, as a maximum, only eat one penguin per hour and 7% of the land is next to the sea.
This calculation is made in such a way that first you multiply two numbers and then add to the result one extra number to get the final result.
Every asterisk in this calculation means some digit from 1 to 9, and every digit is used exactly once. 0 isn't used.
The object is to replace all the asterisks with digits from 1 through 9 so that the whole calculation is correct.
