If a number An consisting of n consecutive digits in ascending order is subtracted from the number An' obtained by reversing the digits of An, then the difference is always a constant. This constant is termed as the 'Unique number' Un as reported by me earlier in. For example, a 3-digit number 345 if subtracted from its reverse 543, yields a difference of 198. Thus U3 = 198. Another 3-digit number, say, 678 if subtracted from its reverse 876 will also yield the same difference, that is, 198. Thus for any number consisting of 3 consecutive digits, the Unique number U3 is always 198. Similarly for a number consisting of 4 consecutive digits, the Unique number U4 = 3087.
A number divisible by 123456789 must be 0 or bigger than 123456789. It must, therefore have 1 digit or 9 digits (or more). A remainder of 1 makes no difference to the number of digits. In any case, there can be no number of 4 digits that is divisible by 123456789.
4*4=16 sum of 1+6 is 7, difference is 5 so 16 is answer
This sum can be any of 14 (from the number 95 or 59), 12 (from the number 84 or 48), 10 (from the number 73 or 37), 8 (from the number 62 or 26), 6 (from the number 51 or 15), or 4 (from the number 40).

If the number with the digits reversed can have a leading 0 so that it is a 1-digit number, then 16. Otherwise 13.

you are the number 48
A digit is part of a number. the number 23 has two digits 2 and 3.
It is easiest to explain with an example. Suppose you have a number 4627. Then the number obtained by reversing [the order of] its digits is 7264. The difference between them is the bigger number minus the smaller number. So here it would be 7264 - 4627 = 2637.

The smallest two digit number is 00 (a number used as a wire gauge) and the largest is 99, so the difference between the largest and smallest 2-digits numbers is 99 (99 - 00)
