The Correct Option is D

Solution and Explanation

$A LL MS A (LL MS) \rightarrow \frac{4 !}{2 !}=\frac{24}{2}=12$
$L ( AL MS ) \rightarrow 4 !=24$
$M (ALLS) \rightarrow \frac{4 !}{2 !}=\frac{24}{2}=12$
$SA ( MLL ) \rightarrow \frac{3 !}{2 !}=3$
$SL ( ALM ) \rightarrow 3 !=6$
Total words $=12+24+12+3+6=57$
$SMALL \,\,\,\,\,58^{t h}$
$\therefore$ the position of the word $SMALL$ is $58^{t h}$

Permutations and Combinations

Permutation:

Permutation is the method or the act of arranging members of a set into an order or a sequence. 

  • In the process of rearranging the numbers, subsets of sets are created to determine all possible arrangement sequences of a single data point. 
  • A permutation is used in many events of daily life. It is used for a list of data where the data order matters.

Combination:

Combination is the method of forming subsets by selecting data from a larger set in a way that the selection order does not matter.

  • Combination refers to the combination of about n things taken k at a time without any repetition.
  • The combination is used for a group of data where the order of data does not matter.
