Quantitative Aptitiude (CLAT) Percentage

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

2/7

1/3

3/7

2/3

Explanation:

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.
