      Question

      A train takes 73 seconds to cross the bridge of 448

      meters. If this train takes 41 seconds to cross the sign board then find out the length of the train.
      A 484 m Correct Answer Incorrect Answer
      B 574 m Correct Answer Incorrect Answer
      C 563 m Correct Answer Incorrect Answer
      D 624m Correct Answer Incorrect Answer

      Solution

      Let the length of the train be x m. Length of the platform = 448 m As we know, Speed = Distance/time (x + 448)/73 = x/41 41x + 18368 = 73x 73x-41x = 18368 32x = 18368 x = 18368/32 x = 574 m ย  Length of the train is 574 m.
