Soln.
Ans: D

Midpoint is 10. We have to find 20 - 9 - 8 = 3 + 1rd item from the left side. Since the location lies in the left half, the sequence has been reversed in this zone. So the item will be at location 10 - 3 = 7 + 1 from the left in the original series. Which means the item is: F.

Soln.
Ans: B

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 Shubham from the bottom is = 24 - 12 + 1 = 13. Number of students between them is: difference of 13 and 15 (minus 1) = 1
