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

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.

there is no universally accepted definition of art. although commonly used to describe something of beauty, or a skill which produces an aesthetic result, there is no clear line in principle between (say) a unique piece of handmade sculpture, and a mass-produced but visually attractive item. we might say that art requires thought - some kind of creative impulse - but this raises more questions: for example, how much thought is required? if someone flings paint at a canvas, hoping by this action to create a work of art, does the result automatically constitute art?

the correct answer is: a.)it is never appropriate to use acronyms and emoticons in business communication.
