Sir, I’m not able to solve the following questions. Please help.
1.Find the number of numbers lying between 3000 and 8000(including 3000 and 8000)which have at least two digits equal.
2.There are 6 Tasks and 6 Persons. Task 1 cannot be assigned to either person 1 or to person 2, task2 must be assigned to either person 3 or 4. Every person is to be assigned one task. In how many ways can the assignment be done?
3.Let S be the set of 5 digit number formed by the digits 1,2,3,4 and 5 using each digit exactly once, such that exactly two odd positions are occupied by odd digits. What is the sum of the digits in the rightmost position of the numbers in S.?
