In a class of 35 students, Kunal is placed seventh from the bottom, whereas Sujata is placed ninth from the top. Pulkit is placed exactly between the two. What is Kunal's position from Pulkit?
Answer & explanation
Correct answer: option 4
The correct answer is Option (4) → 10
Put all three positions on one scale, counted from the top. A position counted from the bottom is turned round with: position from the top = total − position from the bottom + 1.
Kunal: \(35-7+1=29\)th from the top
Sujata: 9th from the top
Pulkit, midway between 9th and 29th: \(\frac{9+29}{2}=19\)th from the top
Kunal from Pulkit: \(29-19=10\), so Kunal is 10th below Pulkit
