This data sufficiency problem consists of a question and two statements, labeled (1) and (2), in which certain data are given. You have to decide whether the data given in the statements are sufficient for answering the question. Using the data given in the statements, plus your knowledge of mathematics and everyday facts (such as the number of days in a leap year or the meaning of the word counterclockwise), you must indicate whether -

Q. Is the positive integer X divisible by 21?

1. When X is divided by 14, the remainder is 4

2. When X is divided by 15, the remainder is 5

2. When X is divided by 15, the remainder is 5

- a)Statement (1) ALONE is sufficient, but statement (2) alone is not sufficient to answer the question asked.
- b)Statement (2) ALONE is sufficient, but statement (1) alone is not sufficient to answer the question asked.
- c)BOTH statements (1) and (2) TOGETHER are sufficient to answer the question asked, but NEITHER statement ALONE is sufficient to answer the question asked.
- d)EACH statement ALONE is sufficient to answer the question asked.
- e)Statements (1) and (2) TOGETHER are NOT sufficient to answer the question asked, and additional data specific to the problem are needed.

Correct answer is option 'D'. Can you explain this answer?

Step 1 of solving this GMAT DS question: Understand the Question Stem

The question is an

The data is sufficient if we are able to get a DEFINITE YES or a DEFINITE NO from the information given in the statements.

If we get a MAYBE as an answer, the data is NOT sufficient

The question stem states that 'X' is a positive integer.

A number is divisible by 21 if it is divisible by 3 and 7.

Step 2 of solving this GMAT DS question Evaluating Statement (1) ALONE

Statement (1) : When X is divided by 14, the remainder is 4

Statement (1) : When X is divided by 14, the remainder is 4

The number is, therefore, of the form 14k + 4.

It will leave a remainder of 4 when divided by 7. (14k is divisible by 7. When 4 is divided by 7, the remainder is 4.)

It will leave a remainder of 4 when divided by 7. (14k is divisible by 7. When 4 is divided by 7, the remainder is 4.)

This number is definitely not divisible by 7.

To be divisible by 21, the number must be divisible by both 3 and 7. This number is not divisible by 7. Hence, X is not divisible by 21.

To be divisible by 21, the number must be divisible by both 3 and 7. This number is not divisible by 7. Hence, X is not divisible by 21.

We have a DEFINITE NO as the answer to the question using statement 1.

Eliminate choices B, C and E. Choices narrow down to A or D.

Step 3 of solving this GMAT DS question Evaluating Statement (2) ALONE

Statement (2) : When X is divided by 15, the remainder is 5

Statement (2) : When X is divided by 15, the remainder is 5

The number X is of the form 15m + 5

Therefore, the number will leave a remainder of 2 when divided by 3.

Therefore, the number will leave a remainder of 2 when divided by 3.

Hence, it is not divisible by 3.

To be divisible by 21, the number must be divisible by both 3 and 7. This number is not divisible by 3. Hence, X is not divisible by 21.

To be divisible by 21, the number must be divisible by both 3 and 7. This number is not divisible by 3. Hence, X is not divisible by 21.

We have a DEFINITE NO as the answer to the question using statement 2 as well.

Eliminate choice A.
