### Question 1

If the first half of the following series is reversed, then which item is 6th to the right of the 15th item from the right side? The series is:

\$ W F V S 7 X 6 1 O B Y D T R Q J I P H

D

O

Soln.
Ans: C

Midpoint is 10. We have to find 20 - 15 + 6 = 11 + 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 Y.

Soln.
Ans: A

Midpoint is 10. We have to find 20 - 3 - 3 = 14 + 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 - 14) = 16 + 1 from the left in the original series. Which means the item is: %.

### Question 3

Kalpana is ranked 13th from the top and 11th from the bottom among the students who passed the annual examination. If the total number of failed students is 5, how many students appeared in the exam?

A

23

B

32

C

28

D

26

Soln.
Ans: C

Sum of positions of an item from top(right) and bottom(left) of a list is always equal to the sum of the positions of the first and last items. So total passed is = 13 + 11 - 1 = 23. Those appeared = failed + passed = 23 + 5 = 28.
