Given Data

1. In a row of 30 students, Ankit is 18th from the left.
2. Kavita is 20th from the right.

Question

How many students are sitting between Ankit and Kavita?

Answer

6 students.

Solution

1. Calculate sum of ranks: Left + Right = 18 + 20 = 38.
2. Since Total (30) < Sum of ranks (38), this is an overlapping arrangement.
3. Persons between = (Left + Right) - Total - 2.
4. Persons between = (18 + 20) - 30 - 2 = 38 - 30 - 2 = 6.
5. There are 6 students sitting between Ankit and Kavita.
