### Question 1

John is ranked 9th from the top and 7th from the bottom among the students who passed the annual examination. If the total number of failed students is 17, how many students appeared in the exam?

32

**B**

34

**C**

26

**D**

31

**Soln.**

**Ans: A**

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 = 9 + 7 - 1 = 15. Those appeared = failed + passed = 15 + 17 = 32.

### Question 5

If the first half of the following series is reversed, then which item is 9th to the right of the 10th item from the right side? The series is:

**A**

F

**B**

3

**C**

D

**D**

1

**Soln.**

**Ans: B**

Midpoint is 10. We have to find 20 - 10 + 9 = 19 + 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 3.
