19. Five persons P, Q, R, S and T sat around table such that all are facing the centre of the table. P is diametrically opposite to T. R and T are neighbours of Q. If there is only one person to the right of P and to the left of T, then find the possible order in which they sat in anticlockwise direction starting from R. అయిదుగురు వ్యక్తులు P, Q, R, S మరియు T లు ఒక వృత్తాకార బల్ల చుట్టూ, బల్ల కేంద్రానికి అభిముఖంగా కూర్చుని ఉన్నారు. ఒక వ్యాసం వెంబడి T కి ఎదురుగా P ఉన్నాడు. Qకి ఇరుగుపొరుగున (ఇరువైపుల) R మరియు T లు ఉన్నారు. P కి కుడివైపున మరియు T కు ఎడవైపున ఒకే వ్యక్తి ఉంటే, వారు అపసవ్య దిశలో R తో మొదలుగా కూర్చున్న వరుసక్రమం వ్రాయండి.

 

Sure Madhu garu! Here's the easy and copyable answer step-by-step:

Given:

• 5 people: P, Q, R, S, T
• All are facing the centre (important)
• P is diametrically opposite to T
• Q has R and T as neighbours
• Only one person is to the right of P
• Only one person is to the left of T
• We need to find the order in anti-clockwise direction starting from R

Step-by-step arrangement:

Let’s arrange them around a circle:

Let’s fix P first.

Since only one person is to the right of P, and all are facing centre, then:

👉 Right of P (facing centre) means clockwise direction.

So if only one person is on P’s right, then P must be sitting at position such that only one person is clockwise to him. That is possible only if P is at position 4 in the circle (see below).

Let’s number positions clockwise as 1–5 for understanding:

Positions (clockwise): 1 → 2 → 3 → 4 → 5

Try P at position 4

Then right of P (clockwise) = position 5
→ only one person is at his right ✅

P is opposite to T, so T must be at position 1.

Now from statement:

Q has R and T as neighbours

T is at position 1
So Q must be at position 2
→ Then R must be at position 3 ✅

Now we are left with one person: S
The only empty position is position 5 → S

So positions are:

1 - T  
2 - Q  
3 - R  
4 - P  
5 - S

Now write names in anticlockwise order starting from R (position 3):

R → Q → T → S → P

✅ Final Answer (Anti-clockwise from R):

R, Q, T, S, P

You can copy this easily. If needed in Telugu, I’ll write that too.
