In a class of 40 students, Ramesh is placed sixth from the top whereas Pankaj is placed thirteenth from the bottom. Kamlesh is placed exactly in between the two. What is Kamlesh's position from the top in the class?
Answer & explanation
Correct answer: option 1
The correct answer is Option (1) → 17th
Both positions are first written from the same end (the top); a rank from the bottom becomes (total + 1 − rank) from the top.
Ramesh is 6th from the top
Pankaj is 13th from the bottom, that is \(40+1-13=28\), 28th from the top
Kamlesh is midway between them: \(\displaystyle\frac{6+28}{2}=17\), 17th from the top, with 10 students between him and each of them
