Based on the given constraints, there will be two cases in which task 1 is either assigned to one among person 3 or 4 or to one among person 5 or 6 Case 1: Assigning Task 1 to either Person 3 or 4. No. of ways of assigning task 1 = 2 ways No. of ways of assigning task 2 = 1 way Remaining 4 tasks can be assigned among the remaining 4 persons in 4! ways. Therefore, Total number of ways = 2 x 1 x 4! = 48 Case 2: Assigning Task 2 to either Person 5 or 6. No. of ways of assigning task 1 = 2 ways No. of ways of assigning task 2 = 2 ways Remaining 4 tasks can be assigned among the remaining 4 persons in 4! ways. Therefore, Total number of ways = 2 x 2 x 4! = 96 Hence, total number of possible arrangements= 48 + 96 = 144
