Assertion: A hydrogen filled balloon stops using after it has attained a certain height in the sky. Reason: The atmospheric pressure decreases with height and becomes zero when maximum height is attained.
Pavan and Sravan are two persons. If Pavan works with his actual efficiency and Sravan twice of his actual efficiency then it takes 25 days to complete the work. But If Pavan works twice of his actual efficiency and Sravan with his normal efficiency then the work is completed in 20 days. How many days would it take if Sravan alone works with his actual efficiency (in Days)?
