Riddles, one at a time
The Clock in the Water
Top and bottom swap in the water. What time does the real clock show?
7:50
Water flips top and bottom: flip the hands back up.
Hands Apart: 9:45
What is the SMALLER angle between the hands?
The hour hand moves 30° each hour. How far has it gone after 45 minutes?
22.5°
The minute hand is on 9; the hour hand is 3/4 of the way to 10: 3/4 × 30° = 22.5°.
Move One Rod
Move exactly one rod. What is the true equation?
9 − 8 = 1
The top rod of the 7 turns the 3 into a 9.
Inside the Loop: Only One Is In
Which gem is INSIDE the loop?
Count wall crossings on the way to the edge: odd means inside.
A
A line from gem A to the edge crosses the wall an odd number of times; from B, C or D, an even number.
Diamond Window
How many closed areas can you count?
Work outward: circle slices, then the diamond, then the corners.
16
8 corner pieces + 4 pieces round the circle + 4 slices inside it: 16.
