In a certain code language CROWNED is written as PSDVEFO. How will STREAMS be written in the same code?

Solution
The word CROWNED is divided into three pars : CRO , W , NED
I : CRO - PSD
The diagonally opposite element is substituted by its immediate following alphabet in the English alphabetical series.
=> C is substituted by D at its diagonally opposite position. Similarly, R is substituted by S at its diagonally opposite position and O by P.
II : W - V
The middle letter is substituted by its immediate preceding alphabet in the English alphabetical series.
III : NED - EFO
The diagonally opposite element is substituted by its immediate following alphabet in the English alphabetical series.
=> N is substituted by O at its diagonally opposite position. Similarly, E is substituted by F at its diagonally opposite position and D by E
=> CROWNED - PSDVEFO.
Thus, code for STREAMS :
STR - SUT
E - D
AMS - TNB
$\therefore$ STREAMS - SUTDTNB
Ans - (E)
