TS EAMCET · Maths · Permutation Combination
If all the letters of the word 'HANDLE' are permuted in all possible ways and the words (with or without meaning) thus formed are arranged in dictionary order, then the rank of the word 'HELAND' is
- A \(420\)
- B \(422\)
- C \(456\)
- D \(475\)
Answer & Solution
Correct Answer
(B) \(422\)
Step-by-step Solution
Detailed explanation
\( \text{Alphabetical order of letters in 'HANDLE': A, D, E, H, L, N} \) \( \text{Words starting with A: } 5! = 120 \) \( \text{Words starting with D: } 5! = 120 \) \( \text{Words starting with E: } 5! = 120 \) \( \text{Total words before H: } 3 \times 120 = 360 \)…
