DRUNN

Solution:

Concept:

Reverse the word, then shift each letter one step backward in the alphabet.

Explanation:

For

\mathrm{CLOCK}

, reversing gives

\mathrm{KCOLC}

.

Shift each letter back by

1

:

\mathrm{K} \to \mathrm{J}

,

\mathrm{C} \to \mathrm{B}

,

\mathrm{O} \to \mathrm{N}

,

\mathrm{L} \to \mathrm{K}

,

\mathrm{C} \to \mathrm{B}

.

Thus,

\mathrm{CLOCK} \to \mathrm{JBNKB}

.

Now for

\mathrm{MOUSE}

, reversing gives

\mathrm{ESUOM}

.

Shift each letter back by

1

:

\mathrm{E} \to \mathrm{D}

,

\mathrm{S} \to \mathrm{R}

,

\mathrm{U} \to \mathrm{T}

,

\mathrm{O} \to \mathrm{N}

,

\mathrm{M} \to \mathrm{L}

.

So,

\mathrm{MOUSE} \to \mathrm{DRTNL}

.

Answer:

\mathrm{DRTNL}
