A boy asks his father, “*what is the age of grand father?*“.

Father replied “*He is x years old in x^2 years*“,

and

also said, “*we are talking about 20th century my son*“.

What is the year of birth of grandfather?

Best answer

43 squared 1849

44 squared 19 36

45 squaRED 2025

SO SINCE 20 TH CENTURY IS BETWEEN 1899

2000

SO 1936 IS ONLY POSSIBLE SQUARE NUMBER BETWEEN REQUIRED VALUES SO HE

WAS **44 IN 1936**

what is the shortest method to find perfect square between the given range?

pls help

** he was born in 1892**

20th century–>>1900-1999;

if x=44 then x^2=44^2=1936

so he was 44years old in 1936

So he was born in 1936-44=1892
