To fill 8 vacancies there are 15 candidates of which 5 are from ST. If 3 of the vacancies are reserved for ST candidates while the rest are open to all, Find the number of ways in which the selection can be done ?
Correct Answer: 7920
Explanation:
ST candidates vacancies can be filled by
ways = 10
Remaining vacancies are 5 that are to be filled by 12

Total number of filling the vacancies = 10 x 792 = 7920
