AP EAMCET · Maths · Permutation Combination
If all the seven letters of the word LEADING are permuted in all possible ways and the words thus formed are arranged as in the dictionary order, then the word in \(2017^{\text {th }}\) place is
- A ELIGDAN
- B ELNADGI
- C ELINADG
- D ELNDAGI
Answer & Solution
Correct Answer
(B) ELNADGI
Step-by-step Solution
Detailed explanation
When letters of LEADING are arranged in ascending order then letters are A, D, E, G, I, L, N Now, words starts with \(\mathrm{A}\) is \(6 !=720\), ie. \(A\)........ Similarly, words starts with \(D=6 !=720\) Now, words starts with \(E\) is also \(6 !=720\). But total number is…
