So Ayaan came to live with Asad when he was about 2 and a half and Asad was 7, and lived there for three years. Which would make Ayaan 5 and Asad 10. So it's been 17 years, which means Asad is 27 and Ayaan is 22, which is what Shireen said once to Raziya, isn't it? (Oh ho bhabbi, Humaira is 20 years old and Ayaan is 22).
So the question is- how old is Zoya? We know she has a degree in computer science and that she has a job she's taken leave from. And if her job is giving her that much leave she must have been working there a couple years at least, because no entry level employee gets that much vacation time. So I'm thinking she's around 25-26.
What do you guys think? How old do you think Zoya is?
