find the rank of QUEEN . PLEASE EXPLAIN METHOD WISE
+Queen has 5 letters out of which 2 are same (i.e. the letter E)
So basically you have to arrange 5 things out of which 2 are the same.
Lets first arrange this word alphabetically, EENQU
Words starting with E as first letter = 4!
Words starting with N as first letter, 4!/2!
Words starting with QE , 3!
Words starting with QN, 3!/2!
Next word would be QUEEN
Hence rank of the word QUEEN will be 4!+4!/2!+3!+ 3!/2!+1 = 46
