What is his Birthdate?
In the year 1937, a man claimed he was x years of age in the year x². He also stated that if you add the number of his years to the number of his birth month, the results is the square of the day of the month in which he was born.
What's his date of birth? (month, day, and year)

the next square before 1937 is 1936, the square of 44, so he was born in the jear 1892 and would be 45 jears old.
(the next would be 1849, but i don't think he became 131 jears old)
to get the day of his birth, you need to add a number from 1 to 12 to the age, so that it gets a square.
the only possibilitie is 45+4 = 49, the square of 7.
so all in all he was born in April, the 7th in the jear 1892
but wait, as we don't know on wich day he said this, we don't know exactly if he was 45 or 44 jears old...
so if he said this before his birthday, the month would be 5(the day stays 7)
so:
if he said this before the 7th april, he was born on the 7th MAY, as he MUST be still 44;
if he said this after the 7th may, he was born on the 7th April, as he MUST be 45.
and if he said this between these two dates, it's impossible to say, on which day he was born.
Hi Carc...
you have 2 of the 3 date components right

May,7th-1892
x=44=44x44=1936
44=5(May)=49
Sqrt.49=7
May-7th-1892
May 7th, 1892 is correct
so my thinking about when he said this is wrong?
