Seven friends, B, C, D, T, U, V and W, are sitting in a straight line facing north. Only three people sit between C and W. D sits to the immediate left of W. No one sits to the right of B. Only two people sit between B and D. T sits to the immediate right of V. How many people sit between U and T?
सात मित्र B, C, D, T, U, V और W उत्तर दिशा की ओर अभिमुख होकर एक सीधी पंक्ति में बैठे हैं। C और W के बीच केवल तीन व्यक्ति बैठे हैं। D, W के ठीक बाईं ओर बैठा है। B के दाईं ओर कोई नहीं बैठा है। B और D के बीच केवल दो व्यक्ति बैठे हैं। T, V के ठीक दाईं ओर बैठा है। U और T के बीच कितने व्यक्ति बैठे हैं?
Detailed Solution & Logic
Two/ दो
1. No one sits to the right of B
इसका मतलब B सबसे दाईं ओर (position 7) बैठा है।
Positions:
1 2 3 4 5 6 7
_ _ _ _ _ _ B
2. Only two people sit between B and D
B (7) और D के बीच 2 लोग होंगे।
इसलिए D position 4 पर होगा।
1 2 3 D 5 6 B
3. D sits to the immediate left of W
D के तुरंत दाईं ओर W होगा।
तो W position 5 पर होगा।
1 2 3 D W 6 B
4. Only three people sit between C and W
W = position 5
3 लोग बीच में ⇒ C position 1 पर होगा।
C _ _ D W _ B
5. T sits to the immediate right of V
T, V के तुरंत दाईं ओर होगा।
6. बची हुई जगहें:
positions 2, 3, 6
यदि V = 2 ⇒ T = 3
तो U = 6
Final arrangement:
C V T D W U B
7. U और T के बीच कितने लोग हैं?
T = position 3
U = position 6
बीच में: D, W
कुल = 2 लोग
✅ Answer: 2 people
