let xy be the two digit number .
therefore , it is of the form 10x+y.
GIVEN,10x+y=10 ...........(1)
from 1,x=10-y/10......(2)
the number obtained by reversing the order of digits is yx=10y+x
given.10y+x=10x+y+36.
when you solve these equations,you get x=23,y=-13
(verification:x+y=10 (given)
23+(-13)=10
10=10)
