On a particularly boring transatlantic flight, one of the authors amused himself by counting the heads of the people in the seat

xxTIMURxx [149]

Answer:

The answer is 5.

Step-by-step explanation:

Total number of people noticed by author = 28

Total number of black haired people = 27

So, total number of non black haired people = 1

Also given that 6 people had whole row of seats to themselves.

Let x be the number of non black haired people who had a whole row to themselves.

Since there is only one person with non black hair and has a whole row to himself because it is mentioned that one person had a row to himself which is non black haired.

Looking at above information we can say that x = 1.

Now we can say that the number of black haired people who had a whole row to themselves = 6-x

or $6-1=5$
