1. this is a simple question but the questionaire needs us to
   consume time.
   speed of car = 2 * speed of auto.
   auto takes 30 mins then car should take only 15 mins.
   total time = 10 mins + 15 mins = 25 mins = (a)

2. speed of car = 2* speed of auto;
   Ans:25 mins.
   let us consider dat car will go for some distace ‘x’ in 10
   mins.
   so the dist. travelled in car,i.e.,x=10*speed of car.
   x = 10 * 2* speed of auto.
   x = 20 * speed of auto.
   the distance travelled in auto will become 30*speed of auto
   where 30 is time taken to reach office.
   the time taken to travel total dist. in auto is 50 min.
   therefore,
   the time taken by car will be half of that, i.e, 25min.
