Mirror and water images — Logical reasoning for kids

A mirror swaps left and right, so a clock in a mirror shows a different time. Take the time away from 11:60 (which is 12:00). Some capital letters look exactly the same in a mirror, and some look the same in water.

How to think it through

Take it from 11:60 — “a mirror clock shows 12:00 minus the real time”

  1. Mirror clock: 11:60 − the time (3:40 → 8:20). If the answer has 60 minutes, write the next hour.
  2. Same in a mirror (standing mirror line): A H I M O T U V W X Y.
  3. Same in water (upside-down reflection): B C D E H I K O X.

Use it for: Mirror and water image questions in reasoning tests, and symmetry in maths.

Worked example: A clock shows 3:40. What time does it show in a mirror? 8:20

  1. Take the time away from 11:60: 11 − 3 = 8 hours and 60 − 40 = 20 minutes.
  2. The mirror shows 8:20.

Check: 3:40 + 8:20 = 12:00 ✓
