A person takes 5hrs 45 min in walking to a place and ridingback. He would have gained 2hrs by riding both ways. The time he would take to walk both ways is?
Choose the correct choice from the following choices
A) 5 hours 45 min  B) 6 hours 30min  C) 4 hours 50 min  D) 7 hours 45 min  E) 8 hours
----------------------------------------------------------------   Solution 1   ----------------------------------------------------------------   Given that time taken for riding both ways will be 2 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 - 2 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 + 2 hours = 7 hours 45 min   In fact, you can do all these calculations mentally and save a lot of time   which will be a real benefit for you.   7 hours 45 min
