[ alt="10 Aug 2017 shift 2 37" src="//storage.googleapis.com/tb-img/production/18/07/10_Aug_2017_shift_2_37.PNG">

Then we arranged the code in reverse order. So, the code of  BANGALORE  is  NQTGDEDQJ.

The same pattern will be followed to write CHENNAI,

[ alt="10 Aug 2017 shift 2 38" src="//storage.googleapis.com/tb-img/production/18/07/10_Aug_2017_shift_2_38.PNG">

So, CHENNAI will be written as HKFQKCP and its reverse order is PCKQFKH.

Thus, PCKQFKH is the correct answer.
