How much water (in grams) should be added to a 35%-solution of acid to obtain a 10%-solution?
(1) There are 50 grams of the 35%-solution.
(2) In the 35%-solution the ratio of acid to water is 7:13.
  • 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 'A'. Can you explain this answer?

Statement (1): There are 50 grams of the 35%-solution. This statement provides information about the initial amount of the 35%-solution. We know the concentration (35%) and the quantity (50 grams). From this information, we can calculate the amount of acid in the solution (35% of 50 grams) and determine the amount of water in the solution (100% - 35% of 50 grams). With this information, we can calculate how much water should be added to obtain a 10%-solution.
Statement (2): In the 35%-solution, the ratio of acid to water is 7:13. This statement provides information about the ratio of acid to water in the 35%-solution. However, it does not give us any information about the quantity or concentration of the solution. Without knowing the amount or concentration of the solution, we cannot determine the amount of water needed to obtain a 10%-solution.
When we consider both statements together, we know the initial amount of the 35%-solution (50 grams) from Statement (1) and the ratio of acid to water in the solution from Statement (2). With this information, we can calculate the amount of acid and water in the initial solution. However, we still don't have enough information to determine how much water should be added to obtain a 10%-solution. We need to know the desired quantity or final concentration of the solution.
Therefore, Statement (1) alone is sufficient to answer the question, but Statement (2) alone is not sufficient. The correct answer is option A: Statement (1) ALONE is sufficient, but statement (2) alone is not sufficient to answer the question asked.

Statement Analysis:

Statement 1: There are 50 grams of the 35%-solution.
- This statement alone does not provide information on the amount of water needed to dilute the solution.

Statement 2: In the 35%-solution the ratio of acid to water is 7:13.
- This statement alone does not provide enough information to calculate the amount of water needed to dilute the solution.

Combining Statements 1 and 2:
- By combining both statements, we know the initial solution weight (50 grams) and the ratio of acid to water in the solution.
- However, we still do not know the exact amount of acid or water in the initial solution to determine the amount of water needed to dilute the solution.
Therefore, the correct answer is option 'A' as neither statement alone nor both statements together are sufficient to answer the question. Additional information is required to calculate the amount of water needed to dilute the acid solution to 10%.
