Question

The ratio of males to females at

a party is 3:5. There are twelve more females than males. How
many people are at the party?

Answer 1

48 people is the right answer.

Explanation:

Let the number of male and female be 3x and 5x

There are twelve more females than males

According to the above problem,

`5x - 3x=12\\ 2x = 12\\ x = (12)/(2) \\ \boxed{x = 6}`

Therefore, the numbers of male is

`3x = 3 * 6 = 18`

and number of female is

`5x = 5 * 6 = 30`

Hence, total number of people are

`(30 + 18) = 48`

There are 48 people in the party.
