Reasoning and Aptitude

Learning process is dependent on ones ability to think logically and reason quickly and effectively. So Reasoning and logic skills are an important part in our progress as these skills are very useful in our day to day life. In this chapter, we will learn various problems related to reasoning and aptitude.

Problems Based on Inserting a Latter

In these types of problems, you are given two sets of two different words. The last letter of the first word and the first letter of the second word in each problems are left blank. You have to fill that letter which completes both the words.

•              Example: (a) E                                                                             (b) K

(c) T                                                                             (d) L

(e) None of these

Ans.     (b)

Explanation: Clearly the letter ?k? will completed all four words.

RISK, KIND, SICK, KITE

Problems Based on Logical Operators

In these types of problems, we have to read the statements and on the basis of these statements, we have to find out the correct conclusions out of the given conclusions.

•             Example:

Statements:     A = B,   B $\le$ C, C $\ge$ D,   E $\ge$ C

Conclusions:     I.  C > A          II. C $\ge$ A           III. A $\le$ E

(a) only I is true                                                  (b) only II is true

(c) only III is true                                                (d) Both II and III are true

(e) None of these

Ans.     (d)

Explanation: A = B $\le$ C $\ge$ D and A = B $\le$ C $\le$ E

$\Rightarrow \,\,A\le C\,\,and\,\,\,\,A\le \,E$

Problems Based on Cube

On folding a sheet to form a cubical box, we may get following forms:  •               Example:

Choose the box which is similar to the box formed the given sheet of paper (M). (a) only I                                                                       (b) only II

(c) only III                                                                      (d) only I and II

(e) None of these

Ans.     (b)

Explanation: Clearly, R lies opposite to T, M lies opposite to L, S lies opposite to U so only possible box is II.
