Pragati...Tanu....and......Maithelli

Yesterday when I was watching the episode...these three girls were together...
Tanu and Pragati really looks like sisters,Pragati looks elder and Tanu the youngest.
But from any angle Maithelli was not looking 3yrs younger than Pragati and of same age of Tanu.....
What do you think?????

i wonder how pragati and maithli became freinds-if that was in school, because pragati is 4 years older than maithli, i would say maithli and tanu should be of the same age

Sherlock Holmes and james Bond rolled in three.
