Correct Answer - Option 4 : 18

**Given :**

A train 200 metres long is moving at the rate of 40 kmph

**Formula used :**

Time = Distance/speed

**Calculations :**

Let the the time to cross man be 't'

t = 200/(100/9) (distance to cover = length of train and speed = 40 km/h = 100/9 m/s)

⇒ 18 seconds

**∴ Option 4 is the correct choice.**
