In a class of 36 children, Jaspreet’s rank is 18th from the bottom. Disha’s rank is 5th from the top. Vihaan’s rank is exactly between Jaspreet and Disha’s rank. What is Vihaan’s rank from the bottom?

- (a)
25

^{th} - (b)
28

^{th} - (c)
26

^{th} - (d)
15

^{th} - (e)
None of these

Answer: Option A

**Explanation** :

There are 36 children in all and Disha is 5^{th} from the top.

∴ Disha’s rank from bottom = 36 − 5 + 1 = 32^{nd}.

Thus, Disha is 14 places away from Jaspreet.

Vihaan is exactly between Jaspreet and Disha.

Hence, Vihaan’s rank from bottom = 18 + (14/2) = 18 + 7 = 25^{th}

Hence, option (a).

In a queue, Rahul is 19th from the front while Dinesh is 33rd from the end. Shubham is exactly between the two. If there are 85 people in the queue, what position does Shubham occupy from the front?

- (a)
35

- (b)
37

- (c)
38

- (d)
39

- (e)
50

Answer: Option C

**Explanation** :

Rahul is 19^{th} from the fron and Dinesh is 33^{rd} from the end. There are 85 people in the queue.

Number of people between Rahul and Dinesh = 85 – 19 – 33 = 33

Shubham is the exactly between the Rahul and Dinesh, hence Shubham is (33 + 1)/2 = 17 places away from either Rahul or Dinesh.

Rahul---16 people---Shubham---16 people---Dinesh

∴ Shubham’s position from the from = 19 + 17 = 36^{th}.

Hence, option (c).

In a row of boys Bhanu is 21st from the left and Viru is 19th from the right. When they interchange positions, Viru becomes 30th from the right. What is the new position of Bhanu from the left?

- (a)
32

- (b)
35

- (c)
38

- (d)
31

- (e)
34

Answer: Option A

**Explanation** :

Initially Bhanu was 21^{st} from the left. After interchanging position same position (occupied by Viru now) is 30^{th} from the right.

∴ Total number of students = 21 + 30 – 1 = 50.

After exchange Bhanu occpies 19^{th} position from right.

∴ New position of Bhanu from left = 50 – 19 + 1 = 32^{nd}.

**Alternately,**

Viru was originally 19^{th} from the right and then became 30^{th} from the right.

∴ Viru moved left by 11 places.

∴ Bhanu also should have moved right by 11 places.

Therefore, Bhanu’s position from the left after the interchange = 21 + 11 = 32^{nd}.

Hence, option (a).
