Hangal says that after partition he was jailed for 2 years. And then he came to India at the age of 21, so he was born in 1927-28. This is further corroborated by the fact that he himself says that he was 40 when Teesri Kasam was filmed (that was in 1965-66). May be he was 38 or 39 then, so he is perhaps 80 or 82 years old and not 92 as the articles claims at the beginning.
