Question

according to me 

AHVKNUS

$55^{th}$ word of SHUVANK in dictionary?   ( 1 Marks )

• A. AHSNKUV 

• B. AHNKSVU 

• C. AHNKUSV 

• D. AHNKUVS 

Answer 1

A. AHSNKUV  Words are arranged in ascending order. Thus if you take last five letters you get 5! = 120 combinations so our first ywo letters are AH . Now when you arrange last five letters in ascending order you get KNSUV .

So Place K at position 3 you get 4! = 24 combinations

then Place N at position 3 you get 4! = 24 combinations

Then Place S at position 3 and K at position 4  you get 3!= 6 combinations
Total = 54 combinations

55th AHSNKUV

Comments

as Then Place S at position 3 and K at position 4  you get 3!= 6 combinations

answer should be  AHSKNUV
