a train passes a man standing on a platform in 8 seconds and also crosses the platform which is 276 metres long in 20 seconds. the length of the train ( in metres ) is:
multiply(divide(276, subtract(20, 8)), 8)
"explanation : let the length of train be l m . acc . to question ( 276 + l ) / 20 = l / 8 2208 + 8 l = 20 l l = 2208 / 12 = 184 m answer a"
