II. x is divisible by 91). If statement I alone is sufficient to answer the question, but statement II alone is not sufficient.2). If statement II alone is sufficient to answer the question, but statement I alone is not sufficient.3). If both the statements I and II together are needed to answer the question.4). If either statements I alone or statement II alone is sufficient to answer the question.

Answer»

If 4X5X9X need to be DIVISIBLE by 9 then

⇒ 4 + X + 5 + X + 9 + X must be divisible by 9

⇒ 18 + 3X must be divisible by 9

Now 18 is divisible by 9 we have to CHECK 3X

STATEMENT I

If x is divisible by 3 then 3X will be divisible by 9

Statement II

∴ If x is divisible by 9 then 3X will be divisible by 9

EITHER statements I alone or statement II alone is sufficient to answer the question
