If the second half of the following series is reversed, then which item is 5th to the left of the 2th item from the right side? The series is:

R C % W 2 K E S 4 Y L N T F M X G 5 $ Z

Soln.
Ans: d

Midpoint is 10. We have to find 20 - 2 - 5 = 13 + 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 - 13) = 17 + 1 from the left in the original series. Which means the item is: 5.

Z + S 1 K J 7 P H M 3 A X 6 Q I G E F O

Soln.
Ans: a

Midpoint is 10. We have to find 20 - 12 + 7 = 15 + 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 I.
