A. I alone sufficient while II alone not sufficient to answer
B. II alone sufficient while I alone not sufficient to answer
C. Either I or II alone sufficient to answer
D. Both I and II are not sufficient to answer
Answer:C

Explanation: Let x and y be the tens and units digits, respectively. Then, because I. x + y = 8 and x/y = 1/3, 4y = 24 y = 6 is obtained.As a result, x + 6 = 8 and x = 2.II. x/y = 1/3 and xy = 12,x2 = 36 x = 6 is the result of II.As a result, 3y = 6 y = 2.As a result, either I or II is adequate to provide an answer.
