Question

What is the mirror image of the given question figure, when the mirror is placed at the right side of the question figure as shown in the figure?

1. A. (Correct answer)
2. B.
3. C.
4. D.

Correct Answer

Option A — A clock dial with a long arrow pointing up and to the left towards the ten, and a shorter, broader arrow pointing down and to the right towards the five.

Detailed Solution & Explanation

The correct answer is option A.

Key Points

• The mirror stands at the right-hand side of the figure, so the reflection is a left-to-right flip. Top stays at the top, bottom stays at the bottom, and only the horizontal direction reverses.
• On a dial, a left-to-right flip sends a hand at a given clock position to the position the same distance from the twelve on the other side. Reading the original:
  • the long arrow points up and to the right, towards the two — its reflection points up and to the left, towards the ten;
  • the short, broader arrow points down and to the left, towards the seven — its reflection points down and to the right, towards the five.
• The dial itself is symmetric, so the tick marks are unchanged and the arrows alone decide the answer. Only option A shows the long arrow at ten and the short arrow at five.

Additional Information

• The one-line check for a side mirror: the vertical positions of everything stay put and the horizontal ones reverse. Anything that moves up or down has been rotated, not reflected.
• The most common trap in this format is an option that has been turned upside down instead of flipped sideways. That is a top-edge mirror, and it sends a hand at two down towards the four rather than up towards the ten.
• Another frequent distractor is the figure rotated by 180°, which reverses both directions at once. It can be spotted because it moves the arrows vertically as well as horizontally.
• Where two arms differ in length or thickness, use that difference rather than the angles — following the long arrow alone through the reflection is usually enough to settle the answer.
• On a clock face specifically, the mirror image of a time t is 11:60 − t, which is worth knowing for the version of this question that gives the time in words rather than as a picture.
