In a row the total number of students are 45. Arti is 15th from the right end and Ganesh is 11th from the left end. Then they interchange their position and then Arti becomes 34th from the right end. How many students are between Ganesh and Arti? Correct Answer 18

The total number of students = 45

Arti is 15th from the right end and Ganesh is 11th from the left end

So, the number of persons between them = 45 - (11 + 15) = 45 - 26 = 19

10 (Ganesh) 19 (Arti) 14

Now, after interchanging their position

Arti becomes 34th from the right end 

There is no overlapping.

10 (Arti) 19 (Ganesh) 14

Now Arti becomes 35 from the right end.

10 (Arti) 18 (Ganesh) 14

So, their are 18 students between them as Arti becomes 34th from the right end

Hence, the correct answer is 18.
