Each of the questions below consists of a question and two statements numbered I and II are given below it. You have to decide whether the data provided in the statements are sufficient to answer the question. Read both the statements and :
Give answer a: If the data in Statement I alone are sufficient to answer the question, while the data in Statement II alone are not sufficient to answer the question.
Give answer b: If the data in Statement II alone are sufficient to answer the question, while the data in Statement I alone are not sufficient to answer the question.
Give answer c: If the data in Statement I alone or in Statement II alone are sufficient to answer the question.
Give answer d: If the data in both the Statements I and II are not sufficient to answer the question.
Give answer e: If the data in both the Statements I and II together are necessary to answer the question.
What is the number of trees planted in the field in rows and columns?
I. Number of columns is more than the number of rows by 4.
II. Number of trees in each column is an even number.
To find the number of trees planted, we need to find the product of number of rows and columns.
Clearly, we cannot find the number of columns and rows from each statement alone, thus by combining both the statements, we get :
Let number of columns = $$c$$ and number of rows = $$r$$
Also, number of rows, $$r$$ is even and $$c=r+4$$
Still, we cannot find the columns and rows.
Thus, both statements even together are insufficient.
