Let 2 digit Number be= XY = 10.X +1.Y
X+Y=15
Reversing the Digit. = YX = 10.Y + 1.X
It is Given
YX - XY =9
10Y +X -10X-Y=9
9Y- 9X= 9
Y-X =1
now we got two equations,,,
X+Y=15
Y-X=1
on solving
Y= 8
X=7
so original number is XY = 78
X+Y=15
Reversing the Digit. = YX = 10.Y + 1.X
It is Given
YX - XY =9
10Y +X -10X-Y=9
9Y- 9X= 9
Y-X =1
now we got two equations,,,

Y-X=1

Y= 8
X=7
so original number is XY = 78
