What is the number? I. The sum of the two digits is 8. The ratio of the two digits is 1 : 3. II. The product of the two digit of a number is 12. The quotient of two digits is 3.	Choices: 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 E) Both I and II are necessary to answer
Let the tens and units digit be x and y respectively. Then,   I. x + y = 8 and	x/y	=	1/3   I gives, 4y = 24 y = 6.   So, x + 6 = 8 x = 2.   II. xy = 12 and	x/y	=	3/1   II gives, x^2 = 36 x = 6.   So, 3y = 6 y = 2.   Therefore, Either I or II alone sufficient to answer.   Option Either I or II alone sufficient to answer
