Question

At a concert, there were 2 children to every grown-up present. what percentage of the audience were children? ​

Answer 1

Answer:

Let x = total number of people at the concert

number of men = (2/5)x

number of children = (2/5)x - 45

number of women = 3[(2/5)x - 45]

Then, (2/5)x + (2/5)x - 45 + 3[(2/5)x - 45] = x

(2/5)x + (2/5)x - 45 + (6/5)x - 135 = x

2x -180 = x

x = 180

Answer 2

Answer:

Let the total people = 100

Total children in every grown up = 2

Total grown up = 1

= 2:1

=2+1=3

= 100/3x2

= 66.66

Ans:- 66.67%
