Option 4 : The data in both the Statements I and II is not sufficient to answer the question.

Assume that the number of rows is R & that of column is C.

∴ the number of trees planted in the field in rows and columns = R × C

From statement 1:

Given that, number of columns is more than the number of rows by 4.

∴ C = R + 4

∴ Using the statement alone we can find infinite number of (C, R) pairs. So no definite conclusion can be drawn.

From statement 2:

Given that, number of trees in each column is an even number.

We need to know the value of C × R.

The information C = 2k does not help to get the value of C × R.

So no definite conclusion can be drawn.

From statement 1 & 2 together:

We have got one relation between C & R from first statement. Another independent equation relating C & R is needed to get definite values of C & R.

So, the data in both the Statements I and II is not sufficient to answer the question.
