In a certain code CLIMATE is written as BUFLJNID. How is ORDERLY written in that code ?

The word CLIMATE is divided into three parts : CLI , M , ATE

I : CLI

Each letter is substituted by its immediate following alphabet in the English alphabetical series.

=> CLI - DMJ

II : M

It is substituted by its immediate preceding alphabet.

=> M - L

III : ATE

Each letter is substituted by its immediate following alphabet in the English alphabetical series.

=> ATE - BUF

Now, to assemble the code what happens is :

Code for part III is written, then code of part II is written and after that code of part I is written in reverse order.

=> BUF+L+JMD

Thus, CLIMATE - BUFLJMD

Following the same pattern :

ORD - PSE

E - D

RLY - SMZ

$$\therefore$$ ORDERLY - SMZDESP
