Answer 1

I am answering 5 questions here. 

1. Position of a person from opposite side = (Total number of person - Position of same person from given side) + 1
= (31 - 13) + 1
= 44 + 1
= 45th
So answer is (d)

2. New position of Ajay from right side = Position fo Ajay from right side before interchanging + (Position of Deepa from left side after interchanging - Position of Deepa from left side before interchanging)
= 13 + (17 - 9)
= 13 + 8
= 21st position from right
So answer is (c)

4. Total number of students = (Position of Mahi from left + Position of Mahi from right ) - 1
= (9 + 38) - 1
47 - 1
46 students
So answer is (c)

8. Same as question 2
Priya's position from right side = 6 + (13 - 5)
= 6 + 8
= 14th 
So answer is (d)

10. Same as question 4
Number of students = (16 + 49) - 1
= 65 - 1
= 64
So answer is (b)
