- A KAMS
- B SAKM
- C AKMS
- D AMSK
Answer & Solution
Correct Answer
(B) SAKM
Step-by-step Solution
Detailed explanation
\(\left(^*\right)\) Given, word is MASK Letters of MASK as per the in dictionary order in dictionary
\[
\Rightarrow \text { AKMS }
\]
\[
\mathrm{A} \rightarrow 3 \text { ! } \mathrm{K} \rightarrow 3 \text { ! , } \mathrm{M} \rightarrow 3 \text { ! }
\]
SAKM \(\rightarrow 19\) th word.
\[
\Rightarrow \text { AKMS }
\]
\[
\mathrm{A} \rightarrow 3 \text { ! } \mathrm{K} \rightarrow 3 \text { ! , } \mathrm{M} \rightarrow 3 \text { ! }
\]
SAKM \(\rightarrow 19\) th word.
