Let the ten’s digit be and the unit’s digit be

I and II:

or and

So, Required number = 68.

II and III:

Solving we get

Required number either 68 or 86.

I and III:

Since, the number obtained by interchanging the digits is greater, the ten’s digit is smaller than the unit’s digit.

Solving we get

So, required number = 68.

Thus, II and either I or III gives the answer.
