In a group of persons, 70% of the persons are male and 30% of the persons are married. If two-sevenths of the males are married, what fraction of the females is single?

व्यक्तियों के एक समूह में, 70% व्यक्ति पुरुष हैं और 30% व्यक्ति विवाहित हैं। यदि पुरुषों का 2/7 भाग विवाहित है, तो महिलाओं का कितना भाग अविवाहित है ?

70% males, so 30% females. If 2/7th of males are married, this means 2/7 (70 %) = 20% males are married. So, 10% females are married (out of 30% total married). So, single females will be 20% out of total 30% females. The fraction is 2/3.
