If 60 out of 30 people over the age of 100 are male, how many are females?

  There are 24 females.

Step-by-step explanation:

We are given that ,

6 out of 30 people over the age of 100 are male.

i.e. The total number of people considered here that are over the age of 100 = 30

Number of males =6

Then , the number of females = (Total people)-(Number of males)

= 30-6

= 24

Hence, the number of females = 24.

Thus , there are 24 females.
