Correct answer: (B) 90 m
Relative speed = (72−36) km/h = 36 km/h = 10 m/s. Distance covered while overtaking = 10×27 = 270 m = length of both trains combined. Length of faster train = 270 − 180 = 90 m.

सही उत्तर: (B) 90 m
सापेक्ष गति = (72−36) किमी/घं = 36 किमी/घं = 10 मी/से। ओवरटेक करते समय तय दूरी = 10×27 = 270 मी = दोनों ट्रेनों की कुल लंबाई। तेज़ ट्रेन की लंबाई = 270 − 180 = 90 मी।
