The Mysterious Letter Riddle

A word I know, six letters it contains,
Remove one letter and twelve remains.
What am I?

👉 The word is “Dozens”.

Explanation:

“Dozens” is a six-letter word (D-O-Z-E-N-S).
When you remove the letter “S”, you are left with “Dozen”.
A “Dozen” means twelve, so even though you removed a letter, the meaning of the word still represents twelve.

The Counterfeit Coin Riddle

Step-by-Step Solution

Step 1: First Weighing

Divide the 12 coins into three groups:
- Group A: 4 coins
- Group B: 4 coins
- Group C: 4 coins (set aside)
Weigh Group A against Group B.

Possible Outcomes:

If the scale balances, the counterfeit coin is in Group C (the 4 coins not weighed).
If the scale tilts, the counterfeit coin is among the 8 coins on the scale, and we now know whether it is heavier or lighter.

Step 2: Second Weighing

Take three coins from the suspected group (either Group C if the first weighing balanced, or the tilting group if not).
Weigh them against three known good coins.

Possible Outcomes:

If the scale balances, the counterfeit coin is the one left out.
- Since we already know whether the fake is heavy or light from Step 1, we now have the answer.
If the scale tilts, we now know the counterfeit is one of the three being weighed and whether it is heavier or lighter.

Step 3: Third Weighing

Take two of the remaining suspected coins and weigh them against each other.

Possible Outcomes:

If the scale balances, the fake coin is the one left out.
If the scale tilts, we know exactly which one is fake and whether it is heavier or lighter.

Final Answer:

👉 You can always find the counterfeit coin and determine if it’s heavier or lighter in exactly 3 weighings.

You have 12 coins, but one is counterfeit and is either heavier or lighter than the rest.
You also have a balance scale and can only use it three times.

How do you find the counterfeit coin and determine whether it is heavier or lighter?

The Car Problem Riddle

A man drives one mile at 30 mph.
How fast must he drive the second mile to average 60 mph for the total two-mile trip?

👉 It’s impossible.

To average 60 mph over 2 miles, he must complete the trip in 2 minutes (since 2 miles ÷ 60 mph = 2 minutes).

The first mile at 30 mph takes 2 minutes.
That means there is NO TIME LEFT to complete the second mile.

Even if he drove infinitely fast, he still wouldn’t reach the required average speed.

What comes once in a second, twice in a decade, but never in a century?
