Answer 1

Possibility of two digit no whose sum is 10

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

Add 54 to each no mentioned above result is

73,82,91,100,109,118,127,136,145

See after first comma 28 and 82

If you reverse 28 . 82 will come which is 54 more than 28. So 28 is that original number

27 has the digits 2 and seven which equal 9

reversed 27 is 72, and 72 + 9 = 81 :)
