Permutation And Combination:
In a boat, that to be filled by 8 people, there are 4 seats on left and 4 on right. Out of these 8 people 3 insist to sit on left and 2 insist to sit on right. So in how many ways they all can sit.

Question

Answer 1

The number of ways in which we can find seats for the people insisting on sitting on one side of the boat is 4P3*4P2 = 288

The other three people can be arranged in 3! = 6 ways.

Hence, the total number of ways in which they can sit is 288*6 = 1728

Answer 2

The number of ways in which we can find seats for the people insisting on sitting on one side of the boat is 4P3*4P2 = 288

The other three people can be arranged in 3! = 6 ways.
