Granpa was borned in 20 th century 
i.e 1900-2000 
When he was 8 Yrs old then the year was square of a number X. 
Since only the square of number 44 is the number that defines the year in between 1900 and 2000 and its 1936. 
Since the granpa of boy was 8 yrs old so the original year of birth will be 1928.
