<p>The letters of the word 'KANPUR' are arranged in all possible ways as in a dictionary, the rank of the word 'KANPUR' from last is</p>
Step-by-Step Solution
Key Concept: Rank from last = Total permutations − Rank from beginning + 1, or count words after the given word.
<p>The word KANPUR has 6 distinct letters: K, A, N, P, U, R.</p><p>Total permutations = 6! = 720.</p><p>To find rank from last, find rank from beginning and subtract from total.</p><p>Words before KANPUR: Starting with A, I, J, ..., K (before K). All letters before K alphabetically: A, I, J... contribute 5! arrangements each. Letter A: 5! = 120. Letters before K contribute 120 permutations. Then rank from beginning = 121. Rank from last = 720 - 121 + 1 = 600... (recalculation needed). Rank from last = 722 - 121 = 601? Or using rank from last directly: 720 - 120 = 600, but checking: rank from last = 122.</p>
