Aptitude Test Topic: Analytical Reasoning

Analytical Reasoning questions are designed to assess the ability to consider a group of facts and rules, and, given those facts and rules, determine what could or must be true. The specific scenarios associated with these questions are usually unrelated to law, since they are intended to be accessible to a wide range of test takers. However, the skills tested parallel those involved in determining what could or must be the case given a set of regulations, the terms of a contract, or the facts of a legal case in relation to the law. In Analytical Reasoning questions, you are asked to reason deductively from a set of statements and rules or principles that describe relationships among persons, things, or events.

Analytical Reasoning: Placement Arrangements Practice MCQ

Four couples—J, K, L, M—are standing in a line. Their positions are numbered consecutively from 1 to 8, and each person is holding hands with the persons on either side of him or her.

J and J are holding hands.

K and K are not holding hands.

L and L are holding hands.

One of the Ls is at one end of the line, and one of the Ms is at the other end.

Question Statement:

Which one of the following must be true?

At least one J is holding hands with a K.

At least one L is holding hands with a J.

At least one L is holding hands with a K.

At least one M is holding hands with an L.

At least one J is holding hands with an M.

Explanation:

Correct Answer: A

The conditions “J and J are holding hands” and “L and L are holding hands” are naturally symbolized as JJ and LL, respectively. The condition “K and K are not holding hands” can be symbolized as K...K. [The symbol ~(KK) would also work well, but the symbol K...K is more descriptive because it shows the space between the Ks.] The condition “One of the Ls is at one end of the line, and one of the Ms is at the other end” can be symbolized as L=1st/last and M=1st/last. The diagram will consist of eight dashed lines numbered 1 through 8, from left to right:

K ... K

L = First / Last

M = First / Last

No significant conditions can be derived from the given information, and no conditions can be placed on the diagram. So we attack the questions.

We will consider only the diagram with M at the left end and the Ls at the right end. The diagram with the Ls at the left end and the M at the right end is the mirror image, so it will generate the same answer. There are four possible diagrams, one for each of the four possible positions of the condition JJ:

From the condition K...K, we see that in the first diagram there must be a K in position 4, in the second diagram there must be a K in position 2, in the third diagram there must be a K in position 6, and in the last diagram there must be a K in position 4:

Each of these diagrams has a J next to a K. In other words, at least one J must be holding hands with a K. Hence the answer is (A).
