there are 10 subjects and 5 periods
I st period can be filled with any 10 subjects
2nd period can be filled with remaining 9 subjects ( 1 subject is already filled)
3 rd period can be filled with remaining 8 subjects ( 2 subjects are already filled)
4 th period can be filled with remaining 7 subjects ( 3 subjects are already filled)
5 rd period can be filled with remaining 6 subjects ( 4 subjects are already filled)
so total no fo ways we can arrange = 10*9*8*7*6
= 30240 ways
Result : 30240
