Answer:


To find the position of Sanju from the back, we need to first find the total number of students standing in the row.

Finding the total number of students in the row:


To find the total number of students, we can add the position of Manu from the front and the position of Sanju from the back and subtract it from 1.

Total number of students = (Position of Manu from the front + Position of Sanju from the back) - 1

Total number of students = (15 + 17) - 1

Total number of students = 31

Finding the position of Sanju from the back after interchanging position with Manu:


After interchanging positions, Sanju will be standing at the 15th place from the front and Manu will be standing at the 17th place from the back.

To find the position of Sanju from the back, we can subtract the position of Sanju from the front from the total number of students.

Position of Sanju from the back = Total number of students - Position of Sanju from the front + 1

Position of Sanju from the back = 31 - 15 + 1

Position of Sanju from the back = 17

Therefore, Sanju is standing at the 17th place from the back after interchanging positions with Manu.
