Number of words starting with E = 5! = 120 Number of words starting with H = 5! = 120 Number of words starting with M = 5! = 120, but one of these words is MOTHER. Now, number of words with ME = 4! = 24 Number of words with MH = 4! = 24 Number of words with MO = 4! = 24, but one of these words is MOTHER. Now, number of words with MOE = 3! = 6 Number of words with MOH = 3! = 6 Number of words with MOR = 3! = 6 Number of words with MOT = 3! = 6, but one of these words is MOTHER. The first word beginning with MOT is MOTEHR. The second word is MOTERH. The third word is MOTHER. Therefore, rank of MOTHER = 2(120) + 2(24) + 3(6) + 3 = 309

Ishmeet Kaur 8 years, 1 month ago

For ex:if we have given some selected words and ask us to find the possible no. Of words that can be formed then we will use permutation and if we have given various things, say 6 balls, out of which we have to select only 3 balls then we will use combination

Ishmeet Kaur 8 years, 1 month ago

Permutation is an arrangement and combination is for finding the ways in which a particular thing can be selected
