Question

In how many ways can five persons be seated in a row?

• A. $60$
• B. $120$
• C. $24$
• D. $100$

Answer 1

The correct option is B $120$

We have to find total number of arrangements of $5$ persons seated in a row.

It is similar to filling of five vacant places without repetition.


We know that arrangement of $n$ different things can be done in $n!$ ways.

So, arrangements of $5$ persons can be done in $5!=120$ ways.
