Question

write all the 2 digits numbers which when added to 27 get reversed

Answer 1

Two digits numbers are 69 and 96

Answer 2

consider a number with units digit y
and tens digit x
so no 10x+y
given 10x+y+27=10y+x
9y-9x=27
y-x=3
so all those two digit no whose units digit is greater than the tens digit by 3 Wil get reversed when 27 is

added to them
eg 14 +27=41
25+27=52
36+27=63
47+27=74
58+27=85
69+27=96

hope it's helps u.......
