The ratio of boys to girls in a group is 5:3. If there are 24 more boys than girls, work out how many girls there are.

9 girls

Step-by-step explanation:

there are 3 groups of 5 which is 15 boys (3 times 5 equals 15).  there are 3 girls for every 5 boys, this means there is 3 groups of girls, but there are 3 girls in each group instead of 5. 3 x 3 equals 9, so there are 9 girls. Total students equals 15 + 9, or 24.

it will cost dollar $540

the living room is 3 which means if we divide 325/3 then we get $108

therefore if 1part of the living room cost $108 and 3 costed $325

then total 5part of the room will cost 5*108 which gives $540

answer: answer is b.
