This one looked simple...but i got it wrong

22. In the fraction x/y, where x and y are positive integers, what is the value of y?
1. The least common denominator of x/y and 1/3 is 6
2. x=1

Answer is E

Highlight to see the answer!

[moneyman]

(1) says that the LCM of x/y and 1/3 is 6.This is possible when y=6 as well as when y=2.INSUFFICIENT.

(2) No information about y is given so INSUFFICIENT.

Combining both statements will also be insufficient as y will still have 2 values.

So E
