60 minutes

Question:

In the above question, suppose they knew that the cave was going to collapse exactly in  60 minutes and they had to escape within the said time. If Nakula takes the responsibility of bringing all the other four, it would take 75 minutes (if this is what you worked out in previous question). But if you are more intelligent, there is a way to make it in 60 minutes. How?

Answer: Think in a different way. First Nakula and Sahadeva come out (5 minutes). Nakula goes back (5 minutes). Nakula and Arjuna (10), Nakula goes back (5), Bheema and Dharmaraja (25), Sahadeva goes back with torch (5) and finally both youngsters come back (5). Total 60 minutes.
