Select the correct option
A) 1/4 hours  B) 2/4 hours  C) 3/4 hours  D) 5/4 hours  E) 7/4 hours
Let the time required for walk is t hours then Ram Singh will reach at the car in time (4+t), due to this walking of Ram Singh time saving = [5-(4+t)]*2 , here 2 is due to forward motion upto railway station and backward from railway station to the point where the car met to Ram Singh. It is given that time saving = 1/2 hour   so 2[1-t] = 1/2 on solving we get t = 3/4 hours   ANSWER:3/4 hours
