The number of ways in which persons can go in two cars so that there may be in each car, supposing that two particular persons will not go in the same car is:
Explanation for the correct option:
Find the required number of permutations.
We need to arrange persons in two cars such that there are persons in each car and two particular persons will not go in the same car.
So, two persons can be arranged in two cars in different ways.
Now, we have to arrange persons in two cars.
So, the number of ways in which four persons can be selected out of persons is .
Therefore, the total number of ways in which persons can go in two cars so that there may be in each car, supposing that two particular persons will not go in the same car is .
Hence, option is the correct answer.
