$A$ is set of letters of the word 'SARIKA', $B$ is set of letters of the word 'RAKASI', then $A$ and $B$ are

• A. equivalent but not equal
• B. equal but not equivalent
• C. equal and equivalent
• D. neither equal nor equivalent

Answer 1

The correct option is C equal and equivalent

$A=\{A,I,K,S,R\};B=\{A,I,K,S,R\}$
$\Rightarrow n\left(A\right)=n\left(B\right)$ also $A=B$
$\Rightarrow A$ and $B$ are equivalent and equal sets.
