View all questions of this test
odd X odd = odd; even X odd = even; even X even = even
odd ± odd = even; odd ± even = odd; even ± even = even
Statement I:
b and c are odd. ∴ bc is odd
abc + bc is even
∴ abc must be odd.
bc is odd, ∴ a must also be odd.
Statement II:
b is odd. abc is even.
∴ ac is even.
It could be that a is even, c is odd or a is odd, c is even or both even.
∴ Statement I alone is sufficient, but Statement II alone is not sufficient to answer the question.

Problem:
Is 'a' odd?
Statement I:
b and c are odd and abc bc is even.
Statement II:
b is odd and abc is even.
Solution:
To determine whether 'a' is odd, we need to know whether the product of 'a', 'b' and 'c' is odd or even.
Statement I:
abc bc is even.
We can rewrite abc bc as (ab)c bc. Since both 'b' and 'c' are odd, (ab) must be even to make the whole expression even. Therefore, 'a' must be even. However, we cannot determine whether 'a' is odd or even from this statement alone.
Statement II:
abc is even.
If 'abc' is even, then either 'a' or 'b' or 'c' must be even. Since 'b' is odd, it cannot be even. Therefore, either 'a' or 'c' must be even. We cannot determine whether 'a' is odd or even from this statement alone.
Combining both statements:
From Statement I, we know that 'a' is even. From Statement II, we know that 'abc' is even and 'b' is odd. Therefore, either 'a' or 'c' must be even. Since 'a' is even, it cannot be odd. Therefore, 'a' must be even. Hence, both statements together are sufficient to answer the question.
Answer:
Option A. Statement I alone is sufficient, but Statement II alone is not sufficient to answer the question.
Is 'a' odd?
Statement I:
b and c are odd and abc bc is even.
Statement II:
b is odd and abc is even.
Solution:
To determine whether 'a' is odd, we need to know whether the product of 'a', 'b' and 'c' is odd or even.
Statement I:
abc bc is even.
We can rewrite abc bc as (ab)c bc. Since both 'b' and 'c' are odd, (ab) must be even to make the whole expression even. Therefore, 'a' must be even. However, we cannot determine whether 'a' is odd or even from this statement alone.
Statement II:
abc is even.
If 'abc' is even, then either 'a' or 'b' or 'c' must be even. Since 'b' is odd, it cannot be even. Therefore, either 'a' or 'c' must be even. We cannot determine whether 'a' is odd or even from this statement alone.
Combining both statements:
From Statement I, we know that 'a' is even. From Statement II, we know that 'abc' is even and 'b' is odd. Therefore, either 'a' or 'c' must be even. Since 'a' is even, it cannot be odd. Therefore, 'a' must be even. Hence, both statements together are sufficient to answer the question.
Answer:
Option A. Statement I alone is sufficient, but Statement II alone is not sufficient to answer the question.
