Pune is bigger than Jhansi, Sitapur is bigger than Chittor.
Raigarh is not as big as Jhansi, but is bigger than Sitapur.
Which is the smallest ?
In terms of size, we have :
Jhansi < Pune, Chittor < Sitapur, Raigarh < Jhansi, Sitapur < Raigarh.
So, the sequence becomes :
Chittor < Sitapur < Raigarh < Jhansi < Pune.
Clearly, Chittor is the smallest.
