In a row at a ticket counter, Ajay is the 7th from the left and Vinay is 9th from the right. They both interchange their positions. Now Ajay becomes 11th from the left. How many people are there in the row?

- 18
- 19
- 20
- None of these

**Answer: (2) 19**

**Explanation:-**

Ajay is the 7th from the left and Vinay is 9th from the right.

They both interchange their position. Then Ajay become 11th from the left.

Thus, number of people = 7 + (11- 4) + 11 – 1 = 7 + 4 + 9 – 1 = 19

Hence, the number of people is 19.
