Answer:
Turn on the first switch and leave it on for a few minutes. Then, turn it off and turn on the second switch. Now, quickly go into the room with the bulbs. The bulb that is warm but off is controlled by the first switch. The bulb that is on is controlled by the second switch. The bulb that is off and cold is controlled by the third switch.
5. The River Crossing Riddle

6. The Jumbled Words Puzzle

“ALOFT”
Answer:
The word is “FLOAT.”
7. The Mysterious Code Riddle
You have a strange code that reads:
1 = A, 2 = B, 3 = C, 4 = D, and so on.
Now, using this code, what word does the number sequence 8 5 12 12 15 translate into?
Answer:
The sequence translates into “HELLO,” where 8 = H, 5 = E, 12 = L, 12 = L, and 15 = O.
8. The Coin Puzzle
You have two coins, one of which is fair (heads or tails with equal probability) and the other is biased (it lands heads 75% of the time). You choose a coin at random and flip it three times, getting three heads in a row. What is the probability that the coin you flipped was the biased one?
Answer:
The probability that the coin you flipped was the biased one is about 93.75%. This is calculated using Bayes’ Theorem, which accounts for the prior probabilities of choosing either coin and the likelihood of flipping three heads in a row for each type of coin.
9. The Logical Deduction Puzzle
In a town, there are two types of people: knights and knaves. Knights always tell the truth, and knaves always lie. You meet two people, Alice and Bob. Alice says, “We are both knaves.” Bob says, “Alice is a knight.” What are Alice and Bob?
Answer:
Alice must be a knave because if she were a knight, her statement “We are both knaves” would be false, which contradicts her being a knight. Since Alice is a knave, Bob’s statement must also be false, meaning Bob is a knight.
10. The Time Riddle
At 3 o’clock, the hour and minute hands of a clock are at right angles to each other. What time will it be next when the hands are again at right angles?
Answer:
The next time the hands will be at right angles will be 3:16:22 (approximately). This is because the hour hand moves slightly after 3 o’clock, and the minute hand needs to be 90 degrees ahead or behind the hour hand.
11. The Family Riddle
A father is 4 times as old as his son. In 20 years, the father will be twice as old as the son. How old are they now?
Answer:
Let the son’s age be x. The father’s age is 4x. In 20 years, the father will be 4x + 20, and the son will be x + 20. The equation is:
4x + 20 = 2(x + 20).
Solving this gives x = 20. So, the son is 20 years old, and the father is 80 years old.
12. The Finger Puzzle
How many fingers do I have if I have four hands, and each hand has 5 fingers?
Answer:
You have 20 fingers. (4 hands × 5 fingers per hand = 20 fingers).
