- A 1120
- B 6720
- C 480
- D 720
Answer & Solution
Correct Answer
(C) 480
Step-by-step Solution
Detailed explanation
There are 7 letters in the word 'SARANAM' of which there are \(3 \mathrm{~A}\) and all other are distinct. The five letter words may consist of (i) all different letters (using S, A, R, N, M) \(\therefore\) Required words \[ =5 !=120 \] (ii) 2 alike and other different (using…
