Possibility of two digit no whose sum is 10

Are

19,28,37,46,55,64,73,82,91

Add 72 to each no mentioned above output is

91,100,109,118,127,136,145,154,163

See first 19 and 91

Assume that two digit no as 19 reverse it 91 will come. The no 92 is 72 more than 19

So 19 is the original

78 Good guess, but 7 + 8 = 15, not 9; so that answer is incorrect. The correct answer is 54. 5 + 4 = 9 45 is 9 less than 54. * * * * * If the sum of the digits of a 2-digit number is 9, and if the order of the digits is reversed the new number will be a multiple of 9 different from the original. It could be bigger or smaller, and the difference could be 18 or 27. For example, 7+2 = 9 and 72 -27 = 45 (which is not 9 but a multiple of 9)

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
