Each of the questions below consists of a question and two statements numbered I and II 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 answer the below questions
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.
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.
c: if the data either in Statement I alone or in Statement II alone are sufficient to answer the question.
d: if the data even in both Statements I and II together are not sufficient to answer the question.
e: if the data in both Statements I and II together are necessary to answer the question.
How many persons are there in a straight line who are facing North ?
I. L is standing exactly in the middle. L is an immediate neighbor of both A and O. Two persons are standing between A and T. T is standing at the second position from the left end of the line. B is standing at the extreme left end of the line.
II. J is standing at the second position from the right end of the line. Five persons are standing between J and F. There are two persons between F and K. K is at one of the extreme ends of the line.
I : B is standing at the left end and T is standing at the second position from the left end of the line
=> T is to the immediate right of B.
Also, 2 persons are standing between A and T, => A is standing at the 5th position from left end.
A is also immediate neighbor of L, who sits in the middle.
=> L is at either 4th position from left end, which means total number of members in the line = 7
Or, L is at 6th position from left end, which means total number of members in the line = 11
Thus, I alone is not sufficient.
II : J is standing at the second position from the right end of the line and five persons are standing between J and F
=> F is standing at 8th position from the right end.
There are two persons between F and K and K is at one of the extreme ends of the line.
=> K is at left end, and F is at 4th position from the left end of the line.
=> Total members in the line = 8 + 4 - 1 = 11
Thus, II alone is sufficient.
