Question

A group consisted of 2 girls for every boy. 24 more girls joined the group. There are now 5 girls for every boy. How many boys are in the group

Answer 1

X = boys

2x+24=5x

Subtract 2 x from each side

24=3x

X=24/3 = 8

there are 8 boys

Answer 2

8 boys are in the group

Explanation:

A group consisted of 2 girls for every boy. 24 more girls joined the group. There are now 5 girls for every boy.

Let 'x' be the number of boys

2 girls for every boy and 24 more girls joined

So number of girls now = 2(number of boys ) + 24

2x + 24

now 5 girls for every boy.

number of girls now = 5 (number of boys)

5x

2x + 24 = 5x

Subtract 2x on both sides

24 = 3x

Divide by 3 on both sides

x= 8

So number of boys in the group = 8
