A positive integer is called a palindrome if it reads the same forward as it does backward. For example, 959 and 8228 are palindromes , whereas 1332 is not neither the first nor the last of a palindrome can be 0 1) Which of the following integers is a palindrome? (A) 550 (B) 2255 (C) 2525 (D) 2552 (E) 5002 2) (D) 2552 reads the same left to right as it reads right to left. How many three-digit palindromes are there ? (A) 19 (B) 20 (C) 90 (D) 100 (E) 810 3) They have the form XYX There are 9 choices for the X and 10 choices for the Y, So that's 9*10 or 90, choice (C) The next two palindromes greater than 50805 are m and p and m < p . what is the value of p – m (A) 10 (B) 90 (C) 100 (D) 110 (E) 210 The next one is m=50905 and the next one after that is p=51015, so p - m = 51015 - 50905 = 110, choice (D) Edwin
