Answer 2

Answer:

555

Step-by-step explanation:

Given : 30% of the people at a concert are female

1295 of the people at the concert are male.

To Find : Work out the number of people at the concert who are female.

Solution :

Let the total number of people at concert be x

We are given that 30% of the people at a concert are female

So, Males = 100% - 30% = 70%

So, no. of males = $70\% \times x = \frac{70}{100}x$

We are given that  1295 of the people at the concert are male.

So,  $1295= \frac{70}{100}x$

$1295 \times \frac{100}{70}=x$

$1850=x$

So, no. of females = Total no. of people - No. of males = 1850-1295 = 555

Hence the number of people at the concert who are female are 555
