Not sure...

Answer 2

Answer:

165

total words formed when the letters of the word INDIAN are arranged = 6!/(2!2!) = 180

words starting with A_ _ _ _ _ = 5!/(2!2!) = 30

"             "          "      D_ _ _ _ _= 5!/(2!2!) = 30

"             "           "      I_ _ _ _ _ = 5!/2! = 60

                                 IA_ _ _ _ = 4!/2! = 12

                                 ID_ _ _ _ = 4!/2! = 12

                                 II_ _ _ _  =  4!/2! = 12

                                 IN_ _ _ _ = 4! = 24

                                 INA_ _ _ = 3! = 6

                                 IND_ _ _ =  3! = 6

ADDING THE NO. OF WORDS TILL II = 156

WORDS TILL IND = 156 + 6 = 162

NOW THE THREE LETTERS CAN BE ARRANGED EASILY WHICH LOOKS LIKE THESE   INDAIN, INDANI, INDIAN

SO THE RANK OF INDIAN IS 162 + 3 =- 165
