Answer 1

Answer:

I think the answer should be 2

Answer 2

Answer:

65

Step-by-step explanation:

let the number be ba

a+b=11-------(1)

By reversing the digits, we get the number ab

ba-ab=9

10b +a-(10a+b)=9

9b-9a=9

or b-a=1----(2)

Solving the 2 equations, we get

2b=12 or b=6 and a=5

Thus, the number is 65.
