A 3 × 3 grid as shown in figure 1 is to be filled with numbers 1 to 9 according to the following rules: - 8 is above 9 and to the right of 2 - 3 is to the right of 7 and above 9 which is to the left of 4 - 2 is to the left of 5 - 7 is above 6 and 2 - 1 is above 5 - ‘To the left o…

Two gears A and B with red arrows are shown below. Gear A rotates in clockwise direction. How many complete rotations does the gear B have to make for the red arrows to meet? [Figure: see page 6 of source PDF]

A greenhouse constructed in the shape of a hemi-spherical dome houses a cuboid structure as shown in the given figure. The top four corners of the cuboid just touch the inside of the hemi-sphere. The diameter of the hemi-sphere is 20 m. The centre of the base of the cuboid and th…

Figure 1 has been constructed by overlapping some alphabets. Assuming the alphabets may be rotated, how many alphabets from figure 2 cannot be overlapped to fit within figure 1? [Figure: see page 6 of source PDF]

Shown below is a fan with red coloured patterns on it. When it rotates, the patterns make circles. How many red circles will be seen when the fan rotates? [Figure: see page 6 of source PDF]
