Actually it should be 18 for girls but I am sure they made up 21 at the last moment to go with cliche climax story. She is surely graduate with her birthday coming late in the year. Looks like makers forgot they shown Jija as 23 years 5 months. So I thought CP too would be 22-23 after that bees-baayis saal dialogue but don't know why makers ruining everything at the last moment. They either clarify CP's age or change Jija's age too as 21-22. It's really weird to think CP being an urban businesswoman was too much after marriage at 21 when Elaichi too being 20-21 did not wanted to marry being a school girl. Seeing her desperation of marriage I assumed her 23-24 but hearing 21 is shocking and weird. Even Happu Singh's eldest daughter Kat who is surely 20-21 was never shown too desperate for marriage. So here they messed up with her to fit into cliche climax story or forgot what they mentioned Jija's age.
Businesswoman and all were fine... Jaldiram could have taught her. I have seen some people who have deep knowledge about finances and investing which is taught by their parents in their young age. So, it was normal.
But I could not understand her desperation for marriage. In TN, it should be 21 for girls to get married. I thought it to be same in Delhi as well.
The way she called Jija 'beta' and 'bhai' looked as if she is 25s...
B - That's confusing. Mostly, they'll use 25 years completion stratedgy for all rituals... Since they could not show girl older than boy, they went for 21.
