Soln.
Ans: D

Midpoint is 10. We have to find 20 - 13 + 7 = 14 + 1th item from the left side. Since the location lies in the right half, reversing the series has no effect in this zone. So counting from the left side, the item is 4.

 C

4

9

Soln.
Ans: A

Sum of positions of an item from top(right) and bottom(left) of a list is always equal to the sum of the positions of the first and last items. So position of Jack from the bottom is = 26 - 13 + 1 = 14. Number of students between them is: difference of 14 and 10 (minus 1) = 3
