Answer:
Number = 91
Step-by-step explanation:
Let my number is "xy", where "x" is on tens place and "y" is on ones place.
From question it is given that
x - y = 8
x = y + 8
since "x" cannot be more than "9", so y could be "0" or "1"
but it is also given that y ≠ 0. So y = 1
and x = 1 + 8 = 9
so number is 91
