  1. 2 second
  2. 4 second
  3. 6 second
  4. 8 second

  Answer And Explanation

  Answer: Option C

  Explanation:

  From the given question,
  we will first calculate the speed of train relative to man,
  => ( 60 + 6 ) = 66 km/hr ( we added 6 because man is running opposite )
  Convert it in metre/second
  $$\begin{aligned} = 66 \times\frac{5}{18} \\ = \frac{55}{3} m/sec\\ \text{Time it will take to pass man }\\ = 110 \times \frac{3}{55} \\ = 6 \text{ seconds} \end{aligned}$$
