700 people are in a group. We'll use F to represent the first initial of their first name, L for the first initial of their last name. Each person is identified with a pair (F,L). At least how many people from this group have the same pairs (F,L) of initials of their first and last names

Answer:

24

Explanation:

We already have a general knowledge that there are 26 different letters in English.

Hence, 26*26=676 different people can be identified uniquely.

Making use of pigeonhole principle,

atleast 700- 676= 24 people will have same pair (F,L) of initials of their first and last name.
