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
The original number would be 28. Swapped around, the number's digits are 82. The difference between the two numbers is 54.
Find a four digit number whose digits will be reversed when multiplied by nine?

Possibility of two digit no whose sum is 17 89 and 98 Reverse of 89 is 98. 98 is 9 less than the original no 89. 89 is original no
"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

Possibility of two digit no whose sum is 17 89 and 98 Reverse of 89 is 98. 98 is 9 less than the original no 89. 89 is original no
If the number with the digits reversed can have a leading 0 so that it is a 1-digit number, then 16. Otherwise 13.
45
An eight digit number with one zero cannot remain the same when its digits are reversed. It must have an even number of 0s.
