Students line up in a queue in which Ashok stands fifteenth from the left and Sakshi is seventh from the right. If they interchange their place, Sakshi would be fifteenth from the right. How many students are there in a queue?

29th

According to the question:

Ashok is 15th from the left and Sakshi is 7th from the right. After they interchange the position Sakshi becomes 15th from right. So, according to the statement we can conclude that total number of students are 15 + 15 - 1 = 29 (as 1 position is being counted twice). Thus, total number of students are = 29
