Kavya once said , 43 ki Anupamma, 33 ki kavya, 30 ki mukku .n all.
I guess there was some references to her marriage years as well I guess some 5-6.. so that matches..
In one flashback of 8 years old during divorce track.they have shown Kavya joining office then.
So 33 is correct as per that..
Now in 2005 prequel Kavya is shown to be I guess only 5-6 years junior to Vanraj...
She gets a call from Anirudh..Now it's shown they were either dating or married by then..
So her show age should be 39-40...
