Rakesh is $17^{\text {th }}$ from the right and Ankit is $15^{\text {th }}$ from the left in a line of students. If they interchange their places, the position of Ankit becomes $19^{\text {th }}$ from the left. How many students are there in the line?
Answer & explanation
Correct answer: option 2
As per the conditions, since the 17th position from the right becomes 19th from the left after interchanging, thus total number of students = 19 + 17 - 1 = 35
The correct answer is Option (2) → 35
