11) Which of the following series follows the given rule?

Rule: The arrows donâ€™t follow any pattern as the image moves one step forward towards the right side.

- 1
- 2
- 3
- 4

**Answer:** C

**Explanation:**

In the first series, as the image moves one step forward, the number of arrows increases by two, e.g. 2, 4, 6 and 8. In the second series, the number of arrows increases by 2, e.g. 1, 3, 5 and 7. In the fourth series, the number of arrows increases by one. Only the arrows of the third series do not follow any specific pattern, e.g. 2,3,2,4.

12) Which of the following series of figures follows the given rule?

Rule: The image formed by curved lines alternates with the image formed by straight lines.

- 1
- 2
- 3
- 4

**Answer:** D

**Explanation:**

Only in the fourth series, an image formed by curved lines alternates with an image formed by straight lines. The images in the first, second and third series do not follow this rule.

13) Which of the following series of different shapes follows the given rule?

Rule: The sides of the shapes in a series increases by one as we move one step forward towards the right side.

- 1
- 2
- 3
- 4

**Answer:** A

**Explanation:**

Only in the first series, the sides of the shapes increase by one as we move one step forward towards the right side, e.g., the shapes in the first series have 3, 4, 5 and 6 sides respectively. In the remaining series, the sides of the shapes are not increasing by one as we move towards the right side.

14) Which of the following series follows the given rule?

Rule: The outer shape disappears gradually, whereas the inner shape appears slowly as the series moves one step forward towards the right side.

- 1
- 2
- 3
- 4

**Answer:** B

**Explanation:**

Only in the second series, the outer shape disappears gradually, and the inner shape appears gradually as we move one step forward towards the right side. The third series follows the reverse order; the outer shape appears gradually, and inner shape disappears gradually. The first and fourth series also do not follow the given rule. So, the answer is option B.

15) Which of the following series of arrows follows the given rule?

Rule: The arrows of the given series can be combined without changing their direction to form a meaningful image.

- 1
- 2
- 3
- 4

**Answer:** A

**Explanation:**

Only the arrows of the first series can be combined without changing their directions to form a meaningful image as shown below:

This image indicates the four cardinal directions, which are generally denoted by their initials N, E, S, and W. The arrows of any other series canâ€™t be combined, without changing their directions, into any meaningful information.
