In the following question, find out the correct answer from the given alternatives.

If in a certain language $\text{MECHANICS}$ is coded as $\text{HCEMASCIN}$, how is $\text{POSTER}$ coded in that code?

1. $\text{OPTSRE}$
2. $\text{SOPRET}$
3. $\text{RETSOP}$
4. $\text{TERPOS}$

Given MECHANICS is coded as HCEMASCIN

• M  $\leftrightarrow$ H   (4)
• E   $\leftrightarrow$  C  (3)
• C   $\leftrightarrow$  E   (2)
• H   $\leftrightarrow$  M  (1)
• A   $\leftrightarrow$  A   (5)
• N   $\leftrightarrow$  S   (9)
•  I    $\leftrightarrow$  C   (8)
• C   $\leftrightarrow$   I    (7)
• S   $\leftrightarrow$   N   (6)

The middle number position has not changed the rest of starting 4 words reverse and last 4 also reverse.

Hence, POSTER will be coded as

• P    $\leftrightarrow$    S   (3)
• O    $\leftrightarrow$    O   (2)
• S    $\leftrightarrow$    P    (1)
• T    $\leftrightarrow$    R    (6)
• E    $\leftrightarrow$    E     (5)
• R    $\leftrightarrow$    T     (4)

Hence, POSTER will be coded as SOPRET
