Mental Aptitude

Introduction

In mental aptitude, there are questions in which you have to think about the question in a logical way. The questions of mental aptitude may be based on numbering of alphabets, completing the patterns of drawings or shapes, finding the missing figures or finding the number patterns. There is a certain relationship between the things given in the patterns. You can easily answer such type of questions by observing that relationship given in the questions.

Number Series

In these problems, numbers given in the series follow a certain pattern and we have to find that certain pattern to write next number of the series.

Observe the following number pattern: 12, 23, 34, 45, ___

In the above number series, each successive number is 11 greater than the preceding number. So next number of the series will be 45 + 11 = 56

Ø    Example:

Fill in the blank by observing the given pattern.

5, 45, 85, ___, 165.

(a) 125                         (b) 120

(c) 135                         (d) All the above

(e) None of these

Answer (a)

Explanation: Numbers are arranged at a gap of 40.

Analysing Patterns

Look at the following images:

Which figure will come in place of blank?

(a)              (b)

(c)                (d) All the above

(e) None of these

Answer (c)

Explanation:             Every image in the given figures rotates clock wise by following the pattern. Hence, the image at the blank space will be.

Ø    Example:

Observe the following pattern and fill in the blank:

(a)                                   (b)

(c)                                  (d) All the above

(e) None of these

Answer (b)

Explanation:             Every image rotates clockwise by following the pattern.

Hence the correct option is (b).
