We could have 9 ways to pick the leader x 8 ways to pick the second place rider x 7 ways to pick the third place rider, etc.
So
9 x 8 x 7 x .....x 3 x 2 x 1 = 9! = 362880 ways to arrange them
so the points are, from P1 to P2, namely P1P2, and from P2 to P3, namely P2P3, and from P3 back to P1, namely P3P1.
10 canoes will they need.
The unitary technique involves first determining the value of a single unit, followed by the value of the necessary number of units.
For example, Let's say Ram spends 36 Rs. for a dozen (12) bananas.
12 bananas will set you back 36 Rs. 1 banana costs 36 x 12 = 3 Rupees.
As a result, one banana costs three rupees. Let's say we need to calculate the price of 15 bananas.
This may be done as follows: 15 bananas cost 3 rupees each; 15 units cost 45 rupees.
Given:
Total candidates = 23+ 2 + 3 = 28
and, Each canoe can hold 3 people.
So, number of canoes will they need
= 28/3
= 9.333
Hence, 10 canoes will they need.
