Non-verbal reasoning: figure series, mirror & water images MCQ - Practice Questions with Answers

The two reflections differ by the line of reflection. In a mirror image, the usual exam assumption is a vertical mirror, so left and right interchange while height stays the same. In a water image, the reflecting surface is horizontal, so top and bottom interchange while the left-right position remains fixed. The two statements describe these two different rules accurately. Treating either one as false would mix up mirror reflection, water reflection and rotation.

One should count repeated elements first when a series is based on arithmetic change, so one, two and three dots require four dots next. Movement means a small part shifts position, such as a dot moving from one corner of a square to the next. Rotation means the figure itself changes facing direction, as in an arrow going up, right, down and left. Elimination means rejecting options with an impossible count or fixed-feature error before comparing style.

One should not trusting the first attractive option. A distractor may have the right outer shape but the wrong inner mark, so the smaller feature can decide the answer. The elimination method says to reject any option that breaks even one fixed feature, such as dot count, shaded-corner position, or arrow orientation. Therefore choosing only by the correct outer shape is the incorrect approach. The proper method is to identify the asked operation and then test count, position, shading, and direction feature by feature.

Position is distinct from orientation. Rotation means the whole figure turns around its centre; an upward arrow can become rightward, downward, and then leftward. Movement is different: a small triangle or circle may move from one corner of a square to the next, but the object may keep pointing upward throughout. The first statement correctly describes rotation, and the second statement correctly describes movement. Keeping these two ideas separate prevents the common error of choosing a shifted object when the rule actually requires a rotated one.

A 90-degree clockwise rotation changes an upward arrow to rightward, then downward, then leftward, and then back upward. The given sequence follows exactly that cycle: up, right, down, left. After four such positions, the next 90-degree turn returns the arrow to its starting direction. Therefore, the next figure should show the arrow pointing upward, while rightward, downward and leftward either repeat an earlier middle step or fail to continue the cycle.
