Instructions

Each question below is followed by two statements A and B. You are to determine whether the data given in the statement is sufficient for answering the question. You should use the data and your knowledge of Mathematics to choose between the possible answers.

Give answer a: if the statement A alone is sufficient to answer the question, but the statement B alone is not sufficient.
Give answer b: if the statement B alone is sufficient to answer the question, but the statement A alone is not sufficient.
Give answer c: if both statements A and B together are needed to answer the question.
Give answer d: if either the statement A alone or statement B alone is sufficient to answer the question.
Give answer e: if you cannot get the answer from the statements A and B together, but need even more data.

Question 136

# Is A an odd number?A. A multiplied by an odd number is equal to an odd number.B. A is not divisible by 2.

Solution

Statement A : A number when multiplied by an odd number results in an odd number, this can only be possible iff the number is an odd number.

Thus, yes, A is an odd number.

Statement A alone is sufficient.

Statement B : Any number which is not divisible by 2 is an odd number.

Thus, A is an odd number.

Statement B alone is also sufficient.

$$\therefore$$ Either statement alone is sufficient.
