Question

Directions: Twenty students are standing in a straight line facing north. Rina is standing sixth from the left end. There are only three students between Rina and Shweta. Radha is standing exactly between Shweta and Rina. Tina is standing sixth to the right of Radha. Anita is standing fourth from the right end of the line. There are more than four students between Rina and Tina.

What is Shweta's position with respect to Anita?

• A. Sixth to the left
• B. Eighth to the left
• C. Seventh to the left
• D. Ninth to the left

Hint:

Determine Shweta's and Anita's positions from the left end, then compare the two numbers.

Answer 1

The Correct Option is C

Instead of just subtracting position numbers, we can verify the direction by counting outward step by step from Anita.

1. Positions fixed from the puzzle: Anita = 17, Shweta = 10 (out of 20 students, left end = position 1).
2. Count from Anita towards the left: One place to the left of Anita is position 16, two places is 15, and so on. Counting down: 16 (1st), 15 (2nd), 14 (3rd), 13 (4th), 12 (5th), 11 (6th), 10 (7th). Position 10 is reached on the 7th step to the left, and that is exactly where Shweta stands.

So Shweta is the seventh person to the left of Anita, confirming option C. \[ \boxed{\text{Seventh to the left}} \]
