Question 5

If the second half of the following series is reversed, then which item is 4th to the left of the 5th item from the right side? The series is:

Q 9 7 H N O G $ B @ F + 2 L R A 3 P J 8

Soln.
Ans: b

Midpoint is 10. We have to find 20 - 5 - 4 = 11 + 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 - 11) = 19 + 1 from the left in the original series. Which means the item is: 8.
