The figure rotates 90
oCW; gets reduced in size and also gets enclosed in a figure with one less number of sides.
4. A cube has six different symbols drawn over its six faces. The symbols are dot, circle, triangle, square, cross and arrow. Three different positions of the cube are shown in figures X, Y, and Z.
From figures X and Y, we conclude that dot, circle, square and cross lie adjacent to the triangle. Therefore, the arrow must lie opposite the triangle. From figures X and Z, we conclude that dot, triangle, arrow and cross lie adjacent to the circle. Therefore, the square must lie opposite the circle. Thus, the arrow lies opposite the triangle, the square lies opposite the circle and consequently, the cross lies opposite the dot.
As analysed above, the symbol opposite the arrow is the triangle.
5. Two positions of a dice are shown below. When number 1 is on the top, what number will be at the bottom?
Number 6 is common to both the positions of the dice. We assume the dice in fig. (ii) to be rotated so that 6 remains on the top face (i.e. face V as per activity 1) and the number 4 in fig. (ii) moves to the FR-RH face (i.e. face I) as in fig. (i), then 5 will move to the RR-RH face (i.e. face II). Clearly, 5 (which lies on face II) and 1 (which lies on face IV) will be opposite to each other. So, when 1 is on the top, then 5 will be at the bottom.
6. Select a suitable figure from the Answer Figures that would replace the question mark (?).
The upper element moves to the lower position; changes its size (reduces in size if initially larger and enlarges if initially smaller); gets laterally inverted and its circular part changes colour (becomes black if initially white and vice-versa). The lower element moves to the upper position; changes its size (reduces in size if initially larger and enlarges if initially smaller); rotates through 180
o and its circular part changes colour (becomes black if initially white and vice-versa).
10. Select a suitable figure from the Answer Figures that would replace the question mark (?).
The smaller element gets enlarged. The larger element reduces in size; gets vertically inverted; moves inside the other element and gets attached to its upper end.
