In a certain code TEMPORAL is written as OLDSMBSP How is CONSIDER written in that code ?

The word is divided into two parts of equal length, i.e. TEMP & ORAL

I : TEMP coded as OLDS

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

=> T is substituted by S at its diagonally opposite position. Similarly E is substituted by D at its diagonally opposite position and similarly for M and P.

II : ORAL coded as MBSP

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

=> O is substituted by P at its diagonally opposite position. Similarly R is substituted by S at its diagonally opposite position and similarly for A and L.

Thus, code for consider will be :

CONS - RMNB

IDER - SFEJ

=> CONSIDER - RMNBSFEJ
