Diagrammatic Reasoning Test 5 Solutions Question 1 There is a central figure and four figures with one in each corner: (i) The central figure changes from a ‘rectangle with rounded corners’ to a rectangle, trapezoid, 12-sided shape and then repeats this order of shapes. (ii) The four figures rotate anticlockwise around the four corners, one corner at a time. Correct Question 2 There are three rows of three arrows. At each step in the series, the first arrow from the first row is added to the end of the second row. The first arrow from the second row is added to the end of the third row; and the first arrow from the third row is added to the end of the first row.

The central figure changes in a series of three: from a horizontal arrowhead; to a vertical arrowhead; and to a curved arrowhead. The eight figures that surround this central figure rotate around it in a clockwise direction by 90-degrees i.e. ‘one side at a time’. Correct Question 4 There are four triangles with one in each corner. At each step of the series: the top right-hand corner triangle rotates by 180-degrees; the top left-hand corner triangle rotates by 90degrees in an anticlockwise direction; the bottom right-hand corner triangle rotates by 180degrees; and the bottom left-hand corner triangle rotates by 90-degrees in an anticlockwise direction. Correct Copyright Practice Aptitude Tests Ltd Question 5 There are three sets of figures: (i) The triangle alternates between black and white, whilst moving one step at a time across a horizontal line; (ii) The number of white squares decreases one at a time until there are no squares and then increases by one square at a time; (iii) The number of black squares increases one at a time up to a maximum of four squares and then decreases by one square at a time. Correct Question 6 Each block in the series contains two columns of three squares. The ‘black shading’ rotates around the “perimeter made by the two columns combined”, by one square at a time. Correct Copyright Practice Aptitude Tests Ltd Question 7 Each block in the series contains three rows of triangles. Firstly, at each step in the series, the central triangle alternates between a black shading and a white shading. Secondly, the ‘black shading’ of the sixth triangle (the third triangle on the second row) moves around the perimeter by one triangle for each step in the series. Thus the ninth triangle (the third triangle on the third row) becomes black, and at the same step the ‘black shading’ of the sixth triangle disappears, leaving its original white shading. Correct Question 8 Each block in the series contains four figures. The flower figure moves around clockwise, one figure at a time, and swops its position with each of these figures as it does so. Correct Copyright Practice Aptitude Tests Ltd Question 9 Each block in the series contains two arrows. At each step in the series: the first arrow rotates anticlockwise by 45-degrees at each step in the series; and the second arrow, which is always horizontal, alternates between pointing right and pointing left. Correct Question 10 Each block in the series contains two to three rows of squares, to which one is added at each step in the series. The first block is added to the bottom left-hand corner and then a subsequent new square is added to each of the other three corners, in an anticlockwise direction.
