Non Verbal Reasoning - Figure Matrix - Discussion

The best way I understand this is to start like this. We are looking to draw a new picture on a black dot using lines that are NOT SHARED by the other 2 images (1st and 2nd block in each row, respectively). Row 1, block 1 has a line pointing up. Row 1, block 2 has a horizontal line. Neither of those images has anything in common so if you combine the lines onto the black circle in Row 1, block 3 that is the image you get.

Moving on to Row 2, block 1. It has a vertical line through it. Block 2 looks as if it reads 3:30 on a clock. What lines do they have in common if any? They have the bottom part of the vertical line in common, therefore, that will NOT be included in the picture in block 3, which leaves only the line at 12:00 (from block 1, and 3:00 (from block 2). Put them together and you have the image in Row 2, block 3.

Lastly, Row 3, block 1. It has a line at 12:00. Block 2 has only a line at 3:00. Neither of them shares the same type of line, therefore, we will use both of those lines to complete the image that belongs in Row 3, block 3.

The given explanation is correct. Assume there are 4 direction around the circle i.e; North, South, East and West.

Now, In the first row, the 1st circle has only the North direction and the 2nd circle has two directions i.e, East and West. So, basically, these two have no common direction. Thus the 3rd circle will have the direction which are Not Common in 1st and 2nd circles. i.e, North, East & West.

Similarly, In the 2nd row direction or the line segments which are not common in the 1st and 2nd circle are North and East.

Therefore, In the third row, the 3rd circle will have North & East direction or line segments because there are no common direction in the 1st amd 2nd circle to be omitted.

So, the answer is A.

Similarly, In the 2nd row direction or the line segments which are not common in the 1st and 2nd circle are North and East.

Therefore, In the third row, the 3rd circle will have North & East direction or line segments because there are no common direction in the 1st amd 2nd circle to be omitted.

So, the answer is A.

See the third circle of two illustrations and assume there are four direction around the circle ie, north, south, east, west.

In the first illustration the south direction is not using for both circle so, SOUTH direction of the third circle also left unused.

Similarly, WEST direction is unused for three circles in the second illustration.

Therefore for third illustration the answer might be the circle with WEST direction unused. So, the answer is option A.

In each row,

After combining the 1st and 2nd figures, exclude the common line segments and copy the rest.

In the 1st row, there is not any common line segments. So all the line segments are combined.

In the 2nd row, south faced line segment is common. So, to exclude the south faced common line segment and copy the rest.

In the 3rd row, after combining the two figures, there is no common lines to exclude, so copy the rest.

In the first row, in the first and second figure, the line segment is not overlapping thus the additional line is formed likewise in the second figure there is an overlapping between the line segments thus one line facing the bottom is removed. In a similar way in third figure there is no overlapping of the line segment thus it is added hence option is A.

@All.

In the 1st column, there are 2 pins that are overlapping. One pin rotates 180° and then again 180.

In 2nd column, left pin rotates 90° clockwise and then that pin rotate again 90°.

Then 3rd column, 3 pin are there, left pin shift 90°. And then again it turns 90° that overlap on right side pin result in the answer A.

From the first row we see that the third picture is a composition of the first two.

For the second row, the same pattern follows on, but we remove the line that is common to both the pictures, which is the bottom one.

For the third row, there are no common pictures, so it's just a simple composition picture of the first two. Hence A.

Simply put, the 3rd picture in each row is the equivalent of all the lines in the previous 2 pictures of the same row added together. However, whenever a line segment of the previous 2 pictures of the same row overlaps, said line gets "eliminated". The overlapping lines do not show up in the 3rd picture.

Look at it like, around black dot with short arms. If the short arm appears in the first two box positioned the same way, it does not make it to the third box. In this case, both arms are not positioned the same way in the two boxes, so they make it to the third.
