I am a three digit number . My tens digit is five more than my ones digit. My hundreds digit is eight less than my tens digit. What I am ? Please solve it ?????

Answer : 
Let we have three digit number =  xyz 
Then from the question we get 
Then we have following statements: 
y = z + 5                                                    ---------------------- ( 1  )

x = y - 8                                                     ---------------------- ( 2 )

Now, the digit y should be greater than 8 but less than 10.

If we take y less than 8, then from (2), the hundreds digit will become negative, that is impossible.
If we take y equal to 8 , then hundreds digit becomes 0, and we obtain a 2-digit number, so it also rejected.

We can't take y = 10 as y is a single digit number.

So, we take y = 9

Now, from (2), x = 9 - 8 = 1

From (1), we get z = 9 - 5 = 4

So, the required number = 194
