Series Reasoning Tricks, Questions

The problem figure set in the completion of series consists of four or five figures numbered A, B, C, D (and E in five figure pattern) followed by five figures numbered as 1, 2, 3, 4 and 5 forming the answer figure set. In other words, the figures in the problem figure set follow a systematic change from left to right. Then one is required to find the nature of change and then decide the next figure (from the figure in answer figure set) subject to the same change. These changes can be of different nature and have been discussed with example.

Series Common Example

Each of the problem figure consist of five figures marker A, B, C, D, and E, you have to select from the answer figure

Problem Figure: 1que-13-ans

Problem Figure: 5que-8-ans

Answer Figure: 5que-8

Solution: (4) In each step, an extra line is added in a fixed pattern.

Problem Figure: 6que-7-ans

Answer Figure: 6que-7

Solution: (4) In the subsequent figure, the smaller arrow rotates anticlockwise through 90º and 45º alternately which the bigger arrow rotates through 135º in clockwise direction.

Problem Figure: 7que-6-ans

Answer Figure: 7que-6

Solution: (4) The position of the two arcs is the same in alternate figure. The small figure is new and move half step anticlockwise each time.

Problem Figure: 8que-5-ans

Answer Figure: 8que-5

Solution: (3) From fig. A to fig. B and fig. C to Fig. D the places of the elements are exchanged and so is their size. Obviously the same trend will from fig E to next one.

Problem Figure: 9que-4-ans

Answer Figure: 9que-4

Solution: (3) Each time a new element is added in the two section of the figure in the bottom and top alternately. The existing elements move sideways.

Problem Figure: 10que-3-ans

Answer Figure: 10que-3

Solution: (5) First three unites in the first column are moved in the subsequent figure. Then three unites in the second column are moved in the next figure. The changes in the first and second column are alternate. The topmost unit is placed at the bottom and the other two simply move upward.

Problem Figure: 11que-2-ans

Answer Figure: 11que-2

Solution: (4) The arrow is turned 90(dig) clockwise in each subsequent figure.

Problem Figure: 12que-1-ans

Answer Figure: 12que-1

Solution: (4) One shaded part (triangle) is moved one step forward. Two shaded parts are moved two steps forward. Three shaded parts are moved three steps in anti-clock direction.
