Answers Test 14:

(01. a)

(02. a)

The letter "D" is associated with the number 6 when it has as reference other letters and other numbers that follow a pattern.

In the last table, there are no reference or comparison points, because it is blank, which would imply a value of "zero" to "D", as no data is available.

SECOND POSSIBILITY:

In each of the first tables, each letter has a value (A = 1 / B = 2 / C = 3 and D = 6). "D" would be the total value of the other letters: 1 + 2 + 3 = 6; When the other spaces of the last table, appear blank, the letter "D" will obtain as a result the sum of empty spaces, that is, ZERO.

(03. c)

(04. b)

1) 5 black, 4 red, 3 black, 2 red, 1 black: A is the answer.

2) 1 black at bottom, 2 black top, 3 black bottom, 4 black top, 5 black at bottom: E is the answer.

3) blue square,

blue square + red circle underneath,

blue square + red circle + green triangle on top,

blue square + red circle + green triangle + black circle underneath,

blue square + red circle + green triangle + black circle + red square on top: C is the answer.

4) Each time one dot is removed so the last box should show one dot. This must be answer D, as it is the only box with a dot in the same location (South) as in the previous box.

5) E & W openings in the square, plus one object at N & S

N & S openings, plus 2 objects at N & S

E & W openings, plus one object at N & S

N & S openings, plus 2 objects at N & S

E & W openings, plus one object at N & S: D is the answer.

6) In each consecutive box one rectangle changes colour. A new colour introduced in a previous box will colour both rectangles in the next box.

Red Red

Red Blue

Blue Blue

Blue Green

Green Green: B is the answer.

7) 8 green dots, 4 red, 4 blue, 4 black

6 green dots, 3 red, 3 blue, 3 black

4 green dots, 2 red, 2 blue, 2 black

2 green dots, 1 red, 1 blue, 1 black

0 green dots, 0 red, 0 blue, 0 black: B is the answer.

8) Each box contains 8 straight lines and a circle.

Only answer C contains 8 straight lines and a circle.

9) The innermost two rectangles are vertical, then horizontal, then vertical again, then horizontal,

So, in the answer they must both be vertical; therefore, E is the answer.

10) One blue square, then two blue squares, then three, then four; so, there must be five blue squares in the answer, which is E.

11) Each box increments by one blue segment (one eight of the square). So, there are 4 segments in box four (half the square is filled).

So, there must be 5 blue segments (5/8th of the square) in the answer, which leaves us with A or D.

But, the diagonal edge of the first segment is also rotating clockwise by 90% each time, so, it should be aligned NW in the answer. Therefore, the answer is D.

12) Items are introduced in this order: black square, black dot, red dot, blue square, green dot. New items are always introduced into the top right corner; therefore, B is the answer.

13) The first box has 7 straight lines, the second 11, the third 15, the fourth 19, and so the fifth box will have 23 lines; so, the answer is C.

14) The first box has one black dot, the second 2, the third 3, the fourth 4 and so; the fifth box will have five black dots, so, the answer is A.

15) The first box has two lines, the second 3, the third 4, the fourth 5 and so; the fifth box will have six lines, so, the answer is C.

16) The first square has 25 black squares, the second has 16, the third 9, the fourth 4 and so, the 5th will have one square (reducing sequence of the square numbers 25, 16, 9, 4, 1). Also, squares are removed from the right and from the bottom; so, the final square will be in the top left corner; thus, the answer is D.

17) The red triangle rotates anticlockwise by one segment each box. The blue triangle rotates by one segment clockwise each box; so, the answer is E.

18) The first box has 5 short lines and no long lines, the second box: 4 short & 1 long, the third box: 3 short & 2 long, the fourth box, 2 short and 3 long. So, each time there is one more long line and one less short line; so, in the fifth box there will be 1 short and 4 long lines: the answer is A.

19) The black line rotates by 45 degrees clockwise each time. The thick red line rotates 45 degrees anticlockwise each time, so, the answer is B.

20) The hardest question! Each time, a shape is removed and replaced by a different shape. The shape to be removed is always directly below the V shape (it points towards the next shape to be removed). So, the next shape to be removed would be the green circle; so, the answer is D.
