Riya is 17th from the front in a queue. She is 19th from the end. Then...
Given: Riya is 17th from the front in a queue and is 19th from the end.

To find: The total number of students in the queue.

Solution:

Let the total number of students in the queue be 'x'.

From the given information, we can say:

The position of Riya from the front = 17

The position of Riya from the end = 19

We know that,

Total number of students in the queue = (Position of Riya from the front) + (Position of Riya from the end) - 1

Putting the given values in the formula, we get:

x = 17 + 19 - 1

x = 35

Therefore, there are 35 students in the queue.

Hence, the correct option is (a) 35.
