Answer:
Here we had 8 seats and 8 people.
one seat out of 8 is a driver seat. Here only 5 (people who can drive are allowed to sit) are allowed for driver seat.
For driver seat arrangement = 5 C 1= 56
for remaining 7 seats arrangement. Except driving person . So we have 7 seats for 7 people
Arrangement = 7!
Total Arrangement = 5 * 7!
