Solution

The correct options are
A
12 seconds

D
1/5 minutes

Speed of the train = 36 km/hr = $\frac{5}{18} \times 18$ = 10 m/s

We know that, Speed = $\frac{D i s t a n c e}{T i m e} \Rightarrow T i m e = \frac{D i s t a n c e}{S p e e d}$
The train needs to cover it's own length in order to cross the man which is 120 m

Therefore, time taken = $\frac{120}{10}$ = 12 seconds
