Make a car no of 4digit.First two digits will be letters next two are no. Repetition are not allowed?

• ans will be
  26*25*10*9
  because there are 26 letters and 0 to 9 i.e 10 digits but repetion not allowed so at 1st position 26 letter,2nd 25 then 3rd 10 digits(0 to 9),4th place 9

• i think ans is.26p2 ×10p2.
  bcz dere r 26 alphabets so no of ways=26p2
  n similarly dere r 10 digits(0 to 9)so no of ways=10p2.hence total noof ways to make a 4 digit named car=26p2× 10p2.

• Here we are going to arrange 4 digits in such a way that the first 2 are alphabets and the remaining 2 are digits
  now total combinations that can be made through the alphabets will be (26 for first place and 25 for second place) ie 26*25
  lly total possible combinations from numbers will be 9*8
  hence total 4 digit numbers can be 26*25*9*8= 46800
