Solution

I : The difference between two digits is 9 only if the digits are 0 and 9.

No. using these digits = 90 and 09.

Since, 90 is the only two digit no. Ans - 90

Thus, I alone is sufficient.

II : Let one's digit be y and ten's digit be x. => Number = 10x + y

x + y = x - y

=> y = 0 & x can be any digit.

Thus, number can be 10,20,30,40...

Thus, II alone is not sufficient.
