Correct Answer: 235
Solution : Given: The speed of two trains = 43 km/h and 51 km/h They are moving in opposite directions. ⇒ Relative speed = (43 + 51) km/h = 94 km/h ⇒ Relative speed in metre/second $= 94 × \frac{5}{18}$ metre/second ⇒ Distance covered by the train in 9 seconds $= 94 × \frac{5}{18} × 9= 235$ m Since this is the distance covered in crossing the man. So, the length of the slower train is 235 metres. Hence, the correct answer is 235.
