Question 1206765
<br>
(revised response, after the other tutor pointed out that part of my response was not right....)<br>
40% of the seats are for children, so 60% are for adults.<br>
60% divided in the ratio 5:7 for seats for men and women respectively means 25% of the seats are for men and 35% are for women.<br>
The ratio of adult seats to children seats is 60:40 = 3:2.<br>
After renovations, the number of children seats is 720; the number of adult seats is (3/2)*720 = 3*360 = 1080.<br>
The total number of seats after the renovations is 720+1080 = 1800.<br>
The number of men seats is 25% of the total, or {{{cross(1080/4 = 270)}}} 1800/4=450.<br>
The number of women seats after the renovations is 35% of the total, or {{{cross(.35(1080) = 378)}}} .35(1800)=630.<br>
ANSWERS:
1080 seats for adults
{{{cross(378)}}} 630 seats for women<br>
