Question

Some students are sitting in a row. Amrit is at 19th position from the left. Rahul is 8th to the left of Amrit and 6th to the left of Dhaval. If Dhaval is 12th from the right, how many students are there in the row?

• A. 28
• B. 29
• C. 30
• D. 31
• E. 32

Hint:

When working with position problems, use the relationships between positions from the left and right to form equations for the total count.

Answer 1

The Correct Option is A

Let the total number of students in the row be \( N \). We are given the following information: - Amrit is at the 19th position from the left. - Rahul is 8th to the left of Amrit, so Rahul is at the \( 19 - 8 = 11 \) position from the left. - Dhaval is 6th to the left of Rahul, so Dhaval is at the \( 11 - 6 = 5 \) position from the left. - Dhaval is also 12th from the right, so: \[ N - 12 + 1 = 5 \quad \Rightarrow \quad N = 28 \] Step 5: Conclusion.
The total number of students in the row is \( \boxed{28} \).
