Answer: 10P3=720
Step-by-step explanation:
Answer:
If you are always included to lead, that leaves 10 students to choose from.
If all that is important is being selected, then there are 10C3 = 120 ways to choose them.
If each selection has a unique duty, then there are 10P3 = 720 ways to assign them their jobs.
The total would be 5 13/20 or 113/20
3*2*3^m*4^m=3^8*2^n
3^m+1*2^2m+1=3^8*2^n
m+1=8
m=7
2m+1=n
n=15
The answer is Rs.43,200.
