Did David solve more questions than Steve in a 2-hour test?

(1) Thrice the number of questions that David solved in the test was greater than 6 less than thrice the number of questions that Steve solved in the test.

(2) Twice the number of questions that David solved in the test was greater than 4 less than twice the number of questions that Steve solved in the test.

(2) Twice the number of questions that David solved in the test was greater than 4 less than twice the number of questions that Steve solved in the test.

- 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;
- 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 are needed.

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

We are given that Thrice the number of questions that David solved in the test was greater than 6 less than thrice the number of questions that Steve solved in the test.

⇒ 3x > 3y − 6

⇒ x > y − 2

We cannot determine whether x > y, since x is greater than a quantity y, which is reduced by a certain amount, 2.

⇒ x > y − 2

We cannot determine whether x > y, since x is greater than a quantity y, which is reduced by a certain amount, 2.

Let us take an example.

Say y = 10, thus x > 10−2 ⇒ x > 8.

If x = 9, then x ≯ y and the answer is No. However, if x = 11, then x > y and the answer is Yes. No unique answer. **Insufficient!**

We are given that Twice the number of questions that David solved in the test was greater than 4 less than twice the number of questions that Steve solved in the test.

⇒ 2x > 2y − 4

⇒ x > y − 2

This is the same inequality that we got in Statement 1.** Insufficient!**

⇒ x > y − 2

This is the same inequality that we got in Statement 1.

Since each statement renders the same inequality, even combining both the statements cannot help. Insufficient!

Each statement renders that same inequality, thus combining both the statements will not help.

You may have deduced a wrong conclusion with the inequality x > y − 2.

We see that x is greater than a number y minus 2; thus, x may or may not be greater than y.

Had the situation been x > y + 2, then it's for certain that x > y; since x is greater than a number (y + 2), then x must be greater than a relatively smaller number y.
