Question

In a row of 40 students, if a is 13th from the left end, find the rank from right end.

Answer 1

28th rank from right end..

Answer 2

The rank of the student from right end will be 28 th.

Step-by-step explanation:

If n number of students are arranged in a row, then the position of the student is x th from the left and y th from the right, the relation among n, x, and y will be  

x + y = n + 1 ........... (1)

Now, given in our case that n = 40 students and x = 13 th and we have to calculate the y th.

Hence, from the equation (1) we get,

13 + y = 40 + 1

⇒ y = 28 th.

So, the rank of the student from the right end will be 28 th. (Answer)
