What is the reverse of add 9?
The reverse of adding 9 is subtracting 9. When you add 9 to a number, you increase its value by 9, and to return to the original number, you must subtract 9 from the result. Thus, the operation that undoes adding 9 is subtraction.

The sum of the digits in a two digit number is 9 If the digits are reversed the new number will be 9 less than the original number What is the original number?
Possibility of two digit no whose sum is 9 18,27,36,45,54,63,72,81 Subract 9 with each no mentioned above output is 9,18,27,36,45,54,63,72 See after 4th comma 54 and 45. Reverse 54=45. now 45 is 9 less than 54. So the original no is 54

How do you know that a numeric is palindrome or not using c or pascal language?
Reverse the digits then check of the new number is the same as the original number.
How to check the divisibility by 23?
Multiply the last digit by 7. Subtract that number from the remaining digits. If that number is divisible by 23, then the original number is divisible by 23.
The sum of the digits in a two digit number is 17 If the digits are reversed the new number will be 9 less than the original number What is the original number?
To total 17 the two digits must be 8 and 9! The original number was 98.

Could you please tell me the Palindrome number checking code?
The most efficient method is to reverse the digits in the number and then check if the reversed number is equal to the original number. In C, we can implement this as follows (using long-hand notation for clarity). Note the use of base (defaulting to base 10) so that we can check values in other bases. bool is_palindrome (unsigned num, unsigned base = 10) { // local variables unsigned rev, digit, digits; // copy the input number digits = num; // initialise the accumulator rev = 0; // repeat while there are digits while (digits) { // extract the low-order digit using modulo (%) operator digit = digit % base; // shift the accumulated digits (if any) one position to the left rev = rev * base; // add on the new digit rev = rev + digit; // shift the remaining digits one position to the right digits = digits / base; } // end while // return true if the number and its reverse are equal return num == rev; }
If the sum of the digits in a two digit number is 10 and when the digits are reversed the new number is 54 more than the original number what is the original number?
Possibility of two digit no whose sum is 10 19,28,37,46,55,64,73,82,91 Now add 54 to each no mentioned above 73,82,91,100,109,118,127,136,145 See after 1st comma 28 and 82 Reverse of 28 is 82. That no 82 is 54 more than the no 28. So 28 is the original

Why does the 1089 maths trick work?
let a, b, c denote the three digits of the original number, then the three-digit number is 100a+10b+c. The reverse is 100c+10b+a. Subtract: (100a+10b+c)-(100c+10b+a) to get 99(a-c). Since the digits were decreasing, (a-c) is at least 2 and no greater than 9, so the result must be one of 198, 297, 396, 495, 594, 693, 792, or 891. When you add any one of those numbers to the reverse of itself, you get 1089
How can you generate a palindrome from a given number?
You write the number and then follow it with the digits in reverse order.
