Possibility of two digit no whose sum is 11
Are
29,38,47,56,65,74,83,92
Subract 45 to each no mentioned above
-16,-7,2,11,20,29,38,47
See after 6th comma 83 and 38
Reverse of 83 is 38. The no 38 is 45 less than 83. Original no is=83 and new no is 38
Find a four digit number whose digits will be reversed when multiplied by nine?
192
To total 17 the two digits must be 8 and 9! The original number was 98.
"If the units digit and the hundreds digit of the number 513 were reversed..." 315 'find the sum of the original number and the new number." 513+315=828
A) If a number has two digits, then the sum of its digits is less than the value of the original two-digit number.
17
The number is 36
47 Impossible problem!

To total 17 the two digits must be 8 and 9! The original number was 98.
If the number with the digits reversed can have a leading 0 so that it is a 1-digit number, then 16. Otherwise 13.
To reverse all the digits of an integer, you can use the following algorithm: Initialize a variable to store the reversed number. While the original number is greater than zero, extract the last digit using the modulus operator (%), append it to the reversed number by multiplying the current reversed number by 10 and adding the extracted digit. Then, remove the last digit from the original number by performing integer division by 10. Finally, handle any potential negative signs if needed.
An eight digit number with one zero cannot remain the same when its digits are reversed. It must have an even number of 0s.
