Let ten's place be =X
&Let the one's place be=Y
:The two digit no. =10x+y
&The reversed no.(no. formed by interchanging the digits)=10y+x
. Acc. To The Question
(10x+y)+(10y+x)=110----------[1]
Also,
(10x+y)-10= 5(x+y)+4------[2]
. Now apply the elimination method to these simple equations and find x&y
