In certain code MEADOWS is written as RVNENFB.How is PRIESTS written in that code ?

The word MEADOWS is divided into three parts : MEA , D , OWS

I : MEA

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

=> MEA - NFB

II : D

It is also substituted by its immediate following alphabet.

=> D - E

III : OWS

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

=> OWS - NVR

Now, to assemble the code what happens is :

code for part III is written in reverse order, then code of part II is written and after that code of part I is written as it is. => RVN+E+NFB

Thus, MEADOWS - RVNENFB

Following the same pattern :

PRI - QSJ

E - F

STS - RSR

$$\therefore$$ PRIESTS - RSRFQSJ
