Question

In a row at a bus stop, 'A' is 7th from the left and 'B' is 9th from the right. They both interchange positions. Now A becomes 11th from the left. How many people are there in the row?

• A. 14
• B. 16
• C. 17
• D. 19
• E. 18

Hint:

When two people interchange, the new position of the first person and the old position of the second person refer to the same physical spot.

Answer 1

The Correct Option is D

Step 1: Analyse options.
- Initially, B's position is 9th from the right. - After interchanging, A moves to B's original spot. - This spot is now described as 11th from the left. - Total people = (Position from Left + Position from Right) - 1. - $Total = (11 + 9) - 1 = 19$.
Step 2: Conclusion.
There are 19 people in the row. Final Answer: (d) 19
