Question 2 What is the sum of the smallest and largest 5-digit palindrome? What is their difference?To find 5-digit palindromes, we Make first and last digit same (’u’ = ‘tth’) Make second and second last digit same (‘t’ = ‘th’) Middle digit can be anything Now, Smallest 5 digit number = 10,000 Smallest 5 digit palindrome = 10,001 Similarly, Largest 5 digit number = 99,999 Largest 5 digit palindrome = 99,999 Sum 10,001 + 99,999 = 110,000 Difference 99,999 – 10,001 = 89,998
