Total number of boys
= (Number of boys in jeevan's row) + (Number of boys in Vikas's row)
= (6 + 1 + 10) + (9 + 1 + 11) = (17 + 21) = 38

Now position of Ashwini = (15 + 6)
= 21st from left

Kamya's new position is 13th from left. But it is the same as Preeti's earlier positon wihich is 6th form the right.
The row consists of (12 + 1 + 5) = 18 girls
Now, Preeti's new position is kamya's earlier position which is 5th from the left.
? Preeti's new position from the right = 18 - 5 + 1
= 13 + 1 = 14

Nayan's position from left = (25 + 1 - 14) = 12th
? Arun's position = (12 - 3)
= 9th from left

Clearly, the girl at the 19th position is exactly in the middle of both the ends.
? Total number of girls = (18 + 1 + 18) = 37
