St1: x > z > Not Sufficient as we do not have information about y
St2: z > y > Not sufficient as we do not have information about x
Combining St1 and St2: x > z > y Let x = 3, z = 2, y = 1 > Are x and y both less than z? No Let x = 3, z = 2, y = 1 > Are x and y both less than z? Yes The main culprit here is that x can be either positive or negative Not Sufficient
Answer: E

Answer: E Why is B not the answer? question is is x<z and y<z B says that y>z which means that the answer of the question is No. why do we care about x? suppose x>z or x<z...our conclusion still holds the same. Please acknowledge

Please acknowledge Hi, St2 states that z > y. You have not interpreted the statement correctly. We need additional information about 'x' for St2 to be sufficient.

Please acknowledge Hi, St2 states that z > y. You have not interpreted the statement correctly. We need additional information about 'x' for St2 to be sufficient. But it doesn't matter. Even if x<z, Statement 2 is sufficient to say both x and y are NOT less than z. I would go with B as well.

Question asks whether both x and y are less than z i.e. whether x < z and y < z? Lets look at St2: z > y > Its as good as saying y < z Now we know that y < z but is x < z? We don't know that. If y < z and x < z then yes both x and y are < z If y < z and x > z then no both x and y are not < z Hence St2 is insufficient.

Thanks for clarifying.
