How many different three-digit numbers can be formed which contain two digits that are the same, and a third digit that is different from the other two?
We have 9 choice of digits for Hundred place (as 0 can't be used), 10 choice of digits for Tens place and 10 choice of digits for Ones place.
Case I - first two digits are same and third digit is different:
9*1*9 = 81
Case II - first and third digits are same and second digit is different:
9*9*1 = 81
Case III - Last two digits are same and first digit is different:
9*9*1 = 81
So there are total of 81 + 81 + 81 = 243 such numbers.
Answer C
