Correct answer: (D) 400
Relative speed = 45 km/h = 12.5 m/s. Distance covered = 12.5 × 108 = 1350 m = sum of lengths. Slower train's length = 1350 − 950 = 400 m.
हिंदी में प्रश्न
75 km/hr की चाल से चलने वाली एक ट्रेन, समान दिशा में 30 km/hr की चाल से चलने वाली दूसरी ट्रेन को 108 सेकंड में पार करती है। यदि तेज़ चाल से चलने वाली ट्रेन की लंबाई 950 m है, तो धीमी चाल से चलने वाली ट्रेन की लंबाई (m में) कितनी है?

सही उत्तर: (D) 400
सापेक्ष चाल = 45 km/h = 12.5 m/s। तय दूरी = 12.5 × 108 = 1350 m = दोनों की लंबाइयों का योग। धीमी ट्रेन की लंबाई = 1350 − 950 = 400 m।
