A person takes 5 hrs 45 min in walking to a place and riding back. He would have gained 4 hrs by riding both ways. The time he would take to walk both ways is?
Select the correct option.
A) 5 hours 45 min	B) 5 hours 55 min	C) 6 hours 45 min	D) 9 hours 45 min	E) 10 hours
----------------------------------------------------------------   Solution 1   ----------------------------------------------------------------   Given that time taken for riding both ways will be 4 hours lesser than   the time needed for waking one way and riding back   From this, we can understand that   time needed for riding one way = time needed for waking one way - 4 hours   Given that time taken in walking one way and riding back = 5 hours 45 min   Hence The time he would take to walk both ways = 5 hours 45 min + 4 hours = 9 hours 45 min   9 hours 45 min
<result>D</result>
