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?

35

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
