Find out from amongst the four alternatives as to how the pattern would appear when the transparent sheet is folded at the dotted line.

     (X)                     (1)                 (2)                 (3)                 (4)

All other figures can be rotated into each other.

Only fig. (5) consists of equal number of black and white pins.

From figures (ii) and (iii), we conclude that 1, 6, 3 and 4 dots lie adjacent to 5 dots. Therefore, 2 dots must lie opposite 5 dots. Conversely, 5 dots must lie opposite 2 dots.

In each step, the symbols move in the order and the symbol that reaches the upper-left position gets replaced by a new one.

In fig. (X), one of the dots lies in the region common to the circle and the triangle only, another dot lies in the region common to the circle, the square and the triangle only and the third dot lies in the rectangle alone. In figures (1) and (4) there is no region common to the circle and the triangle only. In fig. (3) there is no region which lies in the rectangle alone. Only fig. (2) contains all the three types of regions.
