In a row of students, if John, who is 16th from the left, and Johnson, who is 8th from the right, interchange their positions, John becomes 33rd from left. How many students are there in the row? Correct Answer 40
Initially, John is 16th from the left and Johnson is 8th from the right.
We can show the arrangement of students as:

On interchanging their positions, John becomes 33rd from the left. So, the arrangement becomes:
[ alt="10 Sep 10.00 Abhipsa Dasbabu HINDI (1) MADHU images q11aaa" src="//storage.googleapis.com/tb-img/production/18/06/10%20Sep_10.00_Abhipsa%20Dasbabu_HINDI%20%281%29_MADHU_images_q11aaa.PNG">
On interchanging their positions, John should be 8th from the right and Johnson should be 16th from the left. It is also given that the position of John is now 33rd from the left.
Thus, we can clearly see that there are in total 40 students.
So, option 3 is correct.
