y is that.......

hey ur getting confused ..............uday is elder than everyone and next to uday, its nupur then gunjan and diya are of same age..............
remember long long ago.........when they showed class room scenes you might have noticed that uday, nupur, mayank, cj are in one class and gunjan, samrat, diya, benji are in one class. so nupur and gang are seniors to rest of them and uday and diya are not twins and uday calls diya as dids just like that.........and she too calls him as dodo but not bhaiyya.............u know mumbai style .............
but our nupur and gunjan are from morena so they have a habit of calling elders with the name of the relation....................
cleared?????............................

or any information required................if so please be free to ask.............

Hahaha.. confusion confusion!! I have no idea about their ages also in the serial!

pata nahi......?maybe cos they arent used to it???
