All the words that can be formed using alphabets A, H, L, U, R are written as in dictionary (no alphabet is repeated). Then the rank of the word RAHUL is.......
- A 70
- B 71
- C 73
- D 74
Answer & Solution
Correct Answer
(D) 74
Step-by-step Solution
Detailed explanation
Given alphabets are A, H, L, U, R, so the number of words starts with letter \(\mathrm{A}=4 !=24\) The number of words starts with letter \(\mathrm{H}=4 !=2.4\) The number of words starts with letter \(\mathrm{L}=\mathbf{4} !=\mathbf{2 4}\) Now, the next word start with…
