i make an educated guess. Because i saw fariha first time in Manchale Ka Saudi in 1992 and i thing she was 20 year of age at that time. and i saw Arifa in Sona Chandi in 1984 and she was around 18 or 19 years of age. this what i think!
Wow nice guess i never knew this cuz i never saw manchale ka sauda thats a really good guess.
