A boy asks his father what is age of grandfather then father replied he is x years old in x

x years in x^2 year, 20th century
x=44 that year is 1936
so his yr of birth is 1936-44 = 1892
11 years agoHelpfull: Yes(34) No(4)

between 2000 & 2100,
45^2=2025 is only a perfect square year(44^2=1936,46^2=2116)
so grandfather's age is 45 years in 2025
so year of birth=2025-45=1980

20th century means between 1900 to 2000
44^2=1936 is only perfect square in that period
so yr of birth of grand father=1936-44=1892

He is x years old in x^2 years
Find the square root of 2000 that is 44.72
Then,
44 years in 1936, which is 44^2
Grandfather was born 1936 - 44 = 1892

very simple
20th century means 1900 to 2000
grandfather is x yrs old in x^2 yrs
it means the number has to be perfect square b/w 1900 to 2000
which is 44 yrs i.e. in year 1936.
so birth is 1936-44 = 1892

x years old in x^2 years, 20th century
so his age is 45 in the year of 45^2 = 2025
so his yr of birth is 2025-45 = 1980
