Complete the following statement:

In a city of 2,384 people, at least _______ have the same pair of first and last initials.

Answer: 4

Let us suppose no 4 people have the same pair of initials.

Total number of \"pair of initials\"=26*26=676

At most 3 people can share an initial.

Then, maximum number of people =676*3=2028 < 2384

There are more people (more than 2028) so, some more people will have to share an initial.

Now, it is possible that not all initials are shared by more than 4 people as

676*4= 2704 > 2384

So, atleast 4 people have the same pair of initials.

Note- answer may vary based on the interpretation of the question.
