Question 2

If the second half of the following series is reversed, then which item is 2th to the left of the 6th item from the right side? The series is:

G % D L I $ 6 W E S R 8 J F + N 5 M H A

Soln.
Ans: D

Midpoint is 10. We have to find 20 - 6 - 2 = 12 + 1th item from the left side. Since the location lies in the right half, the sequence has been reversed in this zone. So the item will be at location 10 + (20 - 12) = 18 + 1 from the left in the original series. Which means the item is: H.
