In a certain code DESIRABLE is written as JTFEQFMCB, how is DIMENSION written in that code ?

The word DESIRABLE is divided into three pars : DESI , R , ABLE

I : DESI - JTFE

The diagonally opposite element is substituted by its immediate following alphabet in the English alphabetical series.

=> D is substituted by E at its diagonally opposite position. Similarly E is substituted by F at its diagonally opposite position and similarly for S and I.

II : R - Q

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

III : ABLE - FMCB

The diagonally opposite element is substituted by its immediate following alphabet in the English alphabetical series.

=> A is substituted by B at its diagonally opposite position. Similarly B is substituted by C at its diagonally opposite position and similarly for L and E.

Thus, code for DIMENSION :

DIME - FNJE

N - M

SION - OPJT

$$\therefore$$ DIMENSION - FNJEMOPJT
