Answer 1

Answer:

Let the number be in the form of 10x+y,  where x and y are the tens digit and the units digit respectively.  

Applying the first condition:, we get 

x+y=8 ....(1)

Applying the second condition, given in the problem 

10x+y+18=10y+x

⇒9x−9y=−18

⇒x−y=−2 ....(2)

By solving equations (1) and (2), we get  

x=3 and y=5 

Therefore, the number is 35.
