Question

In a row at a bus stop, Amit is 7th from the left and Prakash is 9th from the right. Both of them interchange their positions and thus Amit becomes 11th from the left. How many people are there in that row?

Options

• 18

• 19

• 21

• 20

Answer 1

19

Explanation:

According to question,
Amit is 7th from the left and Prakash is 9th from the right.
After interchanging their positions,
Now Amit becomes 11th from the left.
∴ Total number of people in the row = Amit's position + Prakash's position - 1
Total number of people in the row = 11 + 9 – 1 = 19
