Question

In a row of students, Stephen is sitting 3^rd to the left of Robert. If Robert is 10^th from the leftmost end and 6^th from the rightmost end, then what is the position of Stephen from the rightmost end?

• A. 8^th
• B. 9^th
• C. 7^th
• D. 6^th

Answer 1

The Correct Option is B

Step 1: Defining the Total Number of Students 

Let the total number of students in the row be denoted as N.

Step 2: Finding the Total Number of Students

Robert is 10th from the left and 6th from the right, so the total number of students is:

N = 10 + 6 - 1 = 15

Step 3: Finding Stephen's Position from the Left

Stephen is sitting 3rd to the left of Robert, so Stephen is at position:

10 - 3 = 7

Step 4: Finding Stephen's Position from the Right

Now, to find Stephen’s position from the rightmost end, we calculate:

15 - 7 + 1 = 9

Final Answer: Therefore, the correct answer is (b) 9th.
