Logical Reasoning & Analytical Ability
What is Analytical Reasoning ?
Analytical reasoning involves puzzles in which the
relationship among the groups of objects, people, cities and activities etc. is
given. In such questions, a bunch of information is given that creates a puzzle
in candidate’s mind. The candidates are required to keep in mind these
conditions, analyse the relationship and arrange them in suitable form to answer
the questions. Such questions may deal with sitting arrangement or scheduling
the activities etc.
(1) To solve these questions, candidates need to arrange the
complicated set of information. So, read them carefully.
(2) Rather using lengthy expressions, use initials and symbols to save time.
(3) While reading the set of information, highlight the key words.
(4) Now, arrange the set of information in list, table or diagram.
(5) Try to eliminate the answer choices, then work through the remaining choices
to get the correct answer.
Directions (Q. Nos. 1 to 5) Read the following
information carefully and answer the questions given below.

Directions (Q. Nos. 6 to 7) P, Q, R and S are four gentlemen who are
friends of Eshan. On one Sunday, the four of them visited Eshan at his weekend
(i) The time of each visit was P at 3 O’clock, Q at 4 O’clock, R at 5 O’clock

(iii) At least one of R or S visited Eshan before P.
(iv) R did not visit Eshan between Q and S.
Example 6: Who visited Eshan first ?
Example 7: Who visited Eshan last ?
(d) Data insufficient
Solutions. (Q. Nos. 6 to 7) It is given that P visited at 3 O’clock.
Now, form st. 3, we conclude that P visited at 3 pm. Now, from statement (i), we
conclude that Q has to visit at 4 am otherwise nobody will be able to visit in
between P and Q. Now, if S were to visit at 6 pm, then statement (iv) will get
violated, hence we conclude that S visited at 6 am and R visited at 5 pm.
