If the first half of the following series is reversed, then which item is 6th to the left of the 9th item from the right side? The series is:

8

Soln.
Ans: C

Midpoint is 10. We have to find 20 - 9 - 6 = 5 + 1th 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 - 5 = 5 + 1 from the left in the original series. Which means the item is: F.
