Answer 1

Option : (A)

We have, 

6 objects {K}, {R}, {I}, {S}, {N}, {A}. 

So, 

The total number of words that can be formed using the letters of the word “KRISNA” = 6! 

= 720. 

Writing the letters of the word “KRISNA” alphabetically, 

i.e.,

{A}, {I}, {K}, {N}, {R}, {S}.

Hence, 

There are 323 words before “KRISNA”, then the rank of the word “KRISNA” is (323 + 1) 

= 324.
