✅ Answers & Explanations
There are four boys:
Arun (A), David (D), Giri (G) and Kiran (K)
There are four girls:
Prachi (P), Vaishali (V), Shivani (S) and Malini (M)
Important conditions
No two girls can sit together.
Every boy must have at least one girl adjacent to him.
Prachi and David are adjacent.
Vaishali sits immediately to the right of Kiran.
Arun and Giri are adjacent.
Shivani cannot sit at either end.
Vaishali sits somewhere to the left of David, but she is not adjacent to David.
Step 1: Place Kiran and Vaishali
Vaishali is immediately to the right of Kiran.
Therefore, they form the fixed pair:
Kiran – Vaishali
Since Vaishali must also be to the left of David, David must sit somewhere to the right of this pair.
Step 2: Consider Arun and Giri
Arun and Giri sit next to each other.
They are both boys. Since every boy must be adjacent to at least one girl, the Arun–Giri pair must have girls around it.
Therefore, their possible structure is:
Girl – Arun – Giri – Girl
or
Girl – Giri – Arun – Girl
Arun and Giri can exchange positions, but the remaining arrangement will not change.
Step 3: Place David and Prachi
Prachi must be adjacent to David.
Since Vaishali is to the left of David but is not adjacent to him, David cannot sit immediately after Vaishali.
Also, no two girls can sit together.
The compatible placement of David and Prachi is:
David – Prachi
with Prachi at the right end.
Step 4: Place Shivani
Shivani cannot sit at either end.
She must also be separated from the other girls.
The only compatible place for Shivani is between the Arun–Giri pair and David.
Step 5: Place Malini
After placing all the other people, Malini must occupy the left end.
Thus, the two possible arrangements are:
Arrangement 1
Chair | 1 | 2 | 3 | 4 | 5 | 6 | 7 | 8 |
|---|---|---|---|---|---|---|---|---|
Person | Malini | Kiran | Vaishali | Arun | Giri | Shivani | David | Prachi |
Arrangement 2
Chair | 1 | 2 | 3 | 4 | 5 | 6 | 7 | 8 |
|---|---|---|---|---|---|---|---|---|
Person | Malini | Kiran | Vaishali | Giri | Arun | Shivani | David | Prachi |
The positions of Arun and Giri can be interchanged.
Question 1
The person sitting at the right end is:
In both possible arrangements, Prachi sits in chair 8.
Answer: b) Prachi
Question 2
Which pair is definitely adjacent?
Check the options:
Malini and Arun: Not adjacent.
Arun and Vaishali: Adjacent only in one arrangement.
Shivani and Giri: Adjacent only in one arrangement.
Prachi and David: Adjacent in both arrangements and directly given in the conditions.
Answer: d) Prachi and David
Question 3
How many persons are sitting between David and Kiran?
Kiran sits in chair 2 and David sits in chair 7.
People in chairs 3, 4, 5 and 6 sit between them.
Therefore, four people are between David and Kiran.
Answer: d) 4
Question 4
Who is to the immediate left of Giri?
In Arrangement 1:
Arun – Giri
Therefore, Arun is immediately to the left of Giri.
In Arrangement 2:
Vaishali – Giri – Arun
Therefore, Vaishali is immediately to the left of Giri.
Since Arun and Giri can interchange their positions, the person immediately to the left of Giri is not fixed.
Answer: d) Cannot be determined
Final Answers
b) Prachi
d) Prachi and David
d) 4
d) Cannot be determined
