Question

Choose the correct option from the answer figures which completes the sequence.

• A.

  

• B.

  

• C.

  

• D.

  

Hint:

Split each square into 8 triangles and follow three things: the grey triangle, the hatched triangle and the number of dots on the edges.

Answer 1

The Correct Option is B

Divide each square into 8 triangles and number them clockwise 1 to 8 starting with the triangle just right of the top vertical line.
Grey triangle: 6, 8, 2 (in figures 1, 2, 3), so it moves two places clockwise each time; next it is triangle 4 (bottom, right of the vertical line).
Hatching: figure 1 has vertical hatching at triangle 2, figure 2 has horizontal hatching at triangle 4, figure 3 has vertical hatching at triangle 6. The hatch type alternates and also moves two places clockwise, so figure 4 has horizontal hatching at triangle 8 (top-left, left of the vertical line).
Dots on the edges: 3, 2, 1 so figure 4 has no dots.
Option (2) has the grey triangle at the bottom right, horizontal hatching at the top left and no dots. Options (1) and (3) have a dot and option (4) has the grey triangle in the wrong place.
Answer: (2) grey at bottom-right, horizontal hatching at top-left, no dots
