Question 1
If the first half of the following series is reversed, then which item is 5th to the left of the 7th item from the right side? The series is:
@ 9 T L C % 5 Y E K I R N B M 1 U Z + A
Z
T
C
M
Ans: B
Midpoint is 10. We have to find 20 - 7 - 5 = 8 + 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 - 8 = 2 + 1 from the left in the original series. Which means the item is: T.
