So you
have found the monument to Nicolaus Copernicus, a famous astronomer
who formulated the model of universe that placed the Sun rather than
the Earth at the center of the universe. Copernicus was also a
mathematician so your last task is connected with math.
Task 15
Solve the
task:
The year when Copernicus' "On the Revolutions of the Celestial Spheres" was published is a number consisting of 4 digits. The sum of digits is 13.The third digit is 80% of the second digit, and the first digit is 7 times less than the sum of the fourth digit and the third digit.
Hint: remember that we are asking about a real year connected with Copernicus life, so the first digit must be 1 ;)
