Let the 1st and 2nd digits be x and y x+y=9...................................................1 original no.= 10x+y.............................$ reversed no.=10y+x (10y+x)-(10x+y)=45 9(y-x)=45 (y-x)=45/9=5.........................................................................2 now adding 1 and 2, we get, 2y=14, y=7. Now, putting y=7 in 2, 7-x=5 x=2. now according to $ (i.e., 10X2+7) we have, original no.=27
