Consider the following matrix :

↑↓↑↑↓↑
↓→↓←↑←
←↓→↑

Which one of the following figures fits into the blank part of the above matrix ?

  • A.←↑
  • B.←↓
  • C.→↑
  • D.→↓

Answer: A

The blank is filled by ←↑.

Read each row as three figures of two arrows. Within every row, the first arrows follow the pattern same, same, reversed: up, up, down in row 1 and down, down, up in row 2. So row 3, with left in the first figure and right in the third, needs left in the middle.

The second arrows follow the pattern given, reversed, same: down, up, up in row 1 and right, left, left in row 2. So row 3, with down first and up third, needs up in the middle.

That gives left then up. The other figures get one arrow wrong: left-down repeats the first figure, and right-up and right-down break the first-arrow pattern.
