Question

In a group of persons 70% of the persons are male and 30% of the persons are married if 27th of the mails are married what fraction of the females single

Answer 1

In a group, 70% are Males. So females = 30%

Now, two-seventh of males are married.

Married males = 2/7 * 70% = 20%

Total married persons = 30%

Married females = Total married - Married males = 30% - 20% = 10%

Total females = 30%

Out of every 3 females, one is married and two are unmarried.

so ans is 2/3
