When all the alphabets of 'IMPLEMENTATION' are arranged in the reverse alphabetical order from left to right, then which alphabet is 6th to the right of 13th alphabet from the right end of the new word formed?
M
First list every letter of IMPLEMENTATION exactly as it appears; there are 14 letters: I, M, P, L, E, M, E, N, T, A, T, I, O, N.
Reverse (descending) alphabetical order runs from T down to A, so sort all 14 letters that way, keeping repeats.
The rearranged word is T, T, P, O, N, N, M, M, L, I, I, E, E, A, which still has 14 letters.
To locate the 13th letter from the right in a 14-letter word, convert the count: it is the \(14-13+1=2\)nd letter from the left, namely the second T.
The letter wanted is 6th to the right of this one, so move six places further along: \(2+6=8\)th letter from the left.
Counting T, T, P, O, N, N, M, M, the 8th letter is M.
The technique is to reorder the letters first and then turn every from-the-right count into a from-the-left count so the position is unambiguous. Hence the required alphabet is M.
