Direction: The following question is accompanied by two statements (I) and (II). Determine which statement(s) is/are sufficient to answer the question. Find the initial quantity of milk in jar A. I. The ratio of milk and water in jars A and B is 3:2 and 4:3, respectively. II. 28 litres of the mixture from B is poured into A, and then the ratio of milk and water in jar A becomes 17:12.

1. If the data in statement I alone is sufficient to answer the question, while the data in statement II alone are not sufficient to answer the question.
2. If the data in both statements I and II together are needed to answer the question.
3. If the data either in statement I alone or in statement II alone is sufficient to answer the question.
4. If the data even in both the statements I and II together are not sufficient to answer the question.

Correct answer: If the data in both statements I and II together are needed to answer the question.

Solution

Statement I gives only the composition ratios in jars A and B, so the actual quantity in A cannot be found. Statement II alone also does not give the original amount. Together, they provide enough information to form equations and determine the initial quantity uniquely.
