Below question consists of a question and two statements numbered I and II. Decide whether the data provided in the statements are sufficient to answer the question. What is the number of trees planted in the field in rows and columns? I. The number of columns is 4 more than the number of rows. II. The number of trees in each column is an even number.

1. The data in Statement I alone is sufficient to answer the question, while the data in Statement II alone is not sufficient to answer the question.
2. The data in Statement II alone is sufficient to answer the question, while the data in Statement I alone is not sufficient to answer the question.
3. The data in Statement I alone or in Statement II alone are sufficient to answer the question.
4. The data in both the Statements I and II is not sufficient to answer the question.

Correct answer: The data in both the Statements I and II is not sufficient to answer the question.

Solution

Statement I gives only the relation between rows and columns, not their actual values. Statement II tells us only that each column has an even number of trees, but not how many columns or rows there are. Even together, the exact number of trees cannot be determined uniquely.
