**Correct Answer is Option E):**

3 : 4

**Explanation:**

Let the speed of the train be x km/hr and that of the car be y km/hr.

Then, 120/x+480/y= 8 1/x+4/y=1/15 ....(i)

And, 200/x+400/y=25/3 1/x+2/y=1/24 ....(ii)

Solving (i) and (ii), we get: x = 60 and y = 80.

Ratio of speeds = 60 : 80 = 3 : 4.
