21.5 years (hope my high school math didn't fail me). And honestly, that's no reason for adding new members.
When HwaYoung joined T-ara, many fans were doubtful; and I'm sure she put in a lot of effort to catch up to the rest of the members. She had to learn the dance and singing parts to all previous songs, get use to variety shows and the most difficult of all - also make friends with a group of already extremely bonded friends.

That brings me to the topic of how T-ara has one of the widest spread of age among members. From the least young group of BoRam and Qri, to the middle group of EunJung and HyoMin and finally to the youngest of HwaYoung and JiYeon (SoYeon is sort of like the bridge between the first 2 groups).

In this 7-ara configuration, the age gap between BoRam and JiYeon (widest gap) is already 7 years and 1 month. Seems like their CEO kks is intending to introduce the fourth generation into T-ara by adding the 14-year-old (BoRam is almost twice her age).
