Ranvir graduated from America and came back to India .That was 2 years ago.So now Ranvir is 23-24 years of age(let's assume that since Kinshuk does not look a day older than that.)Alekh is the eldest so Alekh must be around 25-26 years of age or let's say 27 not more than that .Navin is next after Alekh so he must be around 25-26.
So my question is Navin is 25 years of age and has 10 year old kids so when did he marry?At the age of 15-16?It's such a big blooper.Even Avni and Malti are of the same age but Avni has two 10 year old kids whereas Malti has just given birth.
