Riddles that test our logic and observation skills have always fascinated people. One such brain teaser that has recently caught the attention of social media users is this clever family riddle involving Mr. and Mrs. Wang and their extended family. At first glance, the question may appear simple, but a closer look reveals the importance of careful reading and logical deduction.

🧩 The Riddle: Can You Spot the Trick?

Mr. Wang and Mrs. Wang have 3 sons.
Every son has:
– 1 wife
– 1 son
– 1 sister

Question: How many people are in this family?

The options provided are:
A. 10
B. 11
C. 12
D. 14

At first, you might be tempted to multiply each person’s relationships, but that could lead to double-counting. Let’s explore it logically.

👨‍👩‍👦‍👦 Step 1: Count the Core Family

We begin with the basic family:

• Mr. Wang (father)
• Mrs. Wang (mother)
• 3 sons

That gives us 5 people so far.

💍 Step 2: Each Son Has One Wife

Each of the 3 sons is married, so that’s:

• 3 wives

Now we are at 5 + 3 = 8 people.

👶 Step 3: Each Son Has One Son

Each of the 3 sons has a son of his own. That means:

• 3 grandsons

Now the total is 8 + 3 = 11 people.

👧 Step 4: Each Son Has One Sister – But This is the Trick

This part of the riddle can be tricky. It says, “each son has one sister.” It does not say they each have a different sister. It’s very likely—and logically consistent—that they all share one sister.

So, we add just 1 sister, not 3.

That brings the final total to 11 + 1 = 12 people.

✅ Final Answer: 12 People in the Family

So, the correct breakdown of the family is:

1. Mr. Wang
2. Mrs. Wang
3. Son #1
4. Wife of Son #1
5. Son of Son #1
6. Son #2
7. Wife of Son #2
8. Son of Son #2
9. Son #3
10. Wife of Son #3
11. Son of Son #3
12. One shared sister of the 3 sons

Answer: C. 12

💡 What This Riddle Teaches Us

This puzzle isn’t just about math—it’s about reading carefully and understanding shared relationships.

Many people fall for the trap of assuming each son has a separate sister, which would incorrectly lead them to count 3 sisters, not realizing the statement “each son has one sister” could apply to the same girl.

It’s a subtle yet powerful reminder that the way a problem is phrased can change its meaning entirely.
