Option B:

Statement (2) ALONE is sufficient, but statement (1) alone is not sufficient to answer the question asked.

Option 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.

Option E:

Statements (1) and (2) TOGETHER are NOT sufficient to answer the question asked, and additional data specific to the problem are needed.

### Difficulty Level

Easy### Solution

Option A is the correct answer.

### Option Analysis

Let P, T1 and T2 be the price of the meal, tax and tip respectively.

Given, P+T1+T2=30, P=?

Statement I is sufficient: T1+T2=0.2*P —> from the given equation, P+0.2P=30, you can solve for P. This statement is sufficient.

Statement II is sufficient: T1/T2 = 0.25 —> T2=4*T1 —> clearly this will lead to an equation with 2 variables, P+T1+4*T1=30—> P+5*T1=30. We cannot eliminate T1 to get P.

Thus this statement is NOT sufficient.
