NON VERBAL REASONING PART 1

                                                

           Non-verbal reasoning

What exactly is non-verbal reasoning?

Non-verbal reasoning is sometimes called abstract reasoning. It involves solving problems usually presented in diagram or picture form. This means that visual clues are more important than words — hence the term non-verbal. The reasoning bit simply means ‘finding the correct answer’.

With the possible rise in grammar schools, the non-verbal reasoning test has had a high profile in the news recently.

Why test non-verbal reasoning?

Non-verbal reasoning is tested because it shows a variety of skills that are not limited by words and language. These tests can be especially useful for children who find it difficult to talk or communicate verbally, children with English as a second language, and children who are dyslexic. It is also believed that they show a child’s general intelligence and ability without being dependent on maths or English skills.

Tests are used to show how children can learn new ideas and how quickly they can focus to find similarities or differences in the information given. Quick decision-making is important as there may be a time limit. Non-verbal reasoning skills are especially useful for science subjects, maths, engineering, computing, and design. In fact, non-verbal reasoning tests are not limited to school tests; many job interviews also include them.

What will non-verbal reasoning tests involve?

Tests are often made up of a series of multiple-choice questions. Children will be asked to spot the odd one out, the next in the series, or the correct answer in a group of 4 or 5 shapes, pictures, or diagrams. Questions may get harder as the test goes on.

EXAMPLES:

1)Find the number of triangles in the given figure.

A) 28	B) 32
C) 36	D) 40

Answer & Explanation Answer: C) 36

Explanation:

  

The simplest triangles are AML, LRK, KWD, DWJ, JXI, IYC, CYH, HTG, GOB, BOF, FNE and EMA i.e. 12 in number.

The triangles composed of two components each are AEL, KDJ, HIC and FBG i.e. 4 in number.

The triangles composed of three components each are APF, EQB, BQH, GVC, CVJ, IUD, DUL and KPA i.e. 8 in number.

The triangles composed of six components each are ASB, BSG, CSD, DSA, AKF, EBH, GGJ and IDL i.e. 8 in number.

The triangles composed of twelve components each are ADB, ABC, BCD and CDA i.e. 4 in number.

Total number of triangles in the figure = 12 + 4 + 8 + 8 + 4 = 36.

2)Find the minimum number of straight lines required to make the given figure.

A) 11	B) 14
C) 16	D) 17

Answer & Explanation Answer: B) 14

Explanation:

  

The horizontal lines are AK, BJ, CI, DH and EG i.e. 5 in number.

The vertical lines are AE, LF and KG i.e. 3 in number.

The slanting lines are LC, CF, FI, LI, EK and AG i.e. 6 in number.

Thus, there are 5 + 3 + 6 = 14 straight lines in the figure.
