    In a certain code language the word 'NUMBER' is written 'UMHTEL'. How will the word 'SECOND' be written in the language?

    A)  CTQDRB         

    B)  GRQDRB

    C)  CTQFRB         

    D)  GRQFI

    Correct Answer: B

    Solution :

    [b] A real tough one! If we number the letters of the word from 1 to 6, first rearrange the letters in the order 615243. Next, to this reversed order of letters, apply the following alternately: move three letters ahead; go one letter backward. Thus NUMBER first becomes RNEUBM. Then \[R+3=U,\text{ }N-1=M,\] \[E+3=H,\text{ }U1=T,\text{ }B+3=E,\text{ }M-1=L.\]So the final code is UMHTEL. Similarly, SECOND \[\to \] DSNEOC \[\to \] GRQDRB
