Answer 2

Given :

6 rows

24 persons

each row 5 people

To Find :

no. of arrangements

Step-by-step explanation:

first we have to select 5 rows from 6 rows because 24 persons with 5 persons in each row can not be arranged in all 6 rows .

hence selection of 5 rows from 6 :

$_{6} C_{5}$ = $6! /5!( 6 - 5)!$ = 6 ways.

now arranging 24 people in 25 places :

$_{25} P_{24} = 25! / 1! \\= 25!$

Hence total arrangements =

6x(25!)
