<\/p>\n
Mr. Wang and Mrs. Wang have 3 sons.<\/p>\n
So, the first people we can count are the parents and their three sons.<\/p>\n
<\/p>\n
<\/p>\n
That gives us 5 people so far.<\/p>\n
Now the puzzle says that every son has 1 wife.<\/p>\n
Since there are three sons, each one has his own wife.<\/p>\n
<\/p>\n
That means we add 3 wives to the family.<\/p>\n
Now our total is 8 people.<\/p>\n
Next comes another important detail.<\/p>\n
Every son also has 1 son.<\/p>\n
There are three sons in the next generation, one belonging to each of the three original sons.<\/p>\n
So we add 3 more people.<\/p>\n
That brings the total to 11 people.<\/p>\n
At this point, many people may be tempted to choose B. 11.<\/p>\n
But we still have one more detail to consider.<\/p>\n
The puzzle says that every son has 1 sister.<\/p>\n
This is where the wording becomes important.<\/p>\n
It does not say that each son has a different sister.<\/p>\n
The three brothers can all have the same sister.<\/p>\n
For example, imagine Mr. and Mrs. Wang have four children: three boys and one girl.<\/p>\n
Each of the three boys would have one sister.<\/p>\n
But that sister is the same person for all three brothers.<\/p>\n
So we only need to add one sister, not three sisters.<\/p>\n
That brings our final total to 12 people.<\/p>\n
Let\u2019s check the family one more time so there is no double-counting.<\/p>\n
Mr. Wang and Mrs. Wang make 2 people.<\/p>\n
Their three sons make 3 people.<\/p>\n
The three wives of those sons make another 3 people.<\/p>\n
The three sons of those sons make another 3 people.<\/p>\n
And the three brothers share one sister, adding 1 person.<\/p>\n
So the calculation is:<\/p>\n
2 + 3 + 3 + 3 + 1 = 12<\/p>\n
Therefore, the correct answer is C. 12.<\/strong><\/p>\n The trick is not really difficult math.<\/p>\n It is about understanding the relationship between the people and avoiding counting the same person more than once.<\/p>\n If each brother had a different sister, the answer would be higher.<\/p>\n But the puzzle never says that.<\/p>\n In a normal family, several brothers can obviously have the same sister.<\/p>\n That is why one sister is enough to satisfy the statement that every son has 1 sister.<\/p>\n This is also why 11 is so tempting.<\/p>\n You can get to 11 quite easily, but you may forget that the three brothers still need a sister.<\/p>\n On the other hand, choosing 14 usually means assuming that each son has a different sister, which the puzzle never tells us.<\/p>\n So the key is to slow down and think about the wording rather than simply adding every number you see.<\/p>\n At first glance, this family puzzle looks like a simple counting question. But there is a small detail in the wording that can easily make you choose the wrong answer. Take a moment to read the puzzle carefully before doing any math. Mr. Wang and Mrs. Wang have 3 sons.
