Answer 1

Answer:

75

Step-by-step explanation:

The initial number of boys and girls is 20 and 25

so the initial boy to girl ratio is

20/25

the final ratio is 7/8

from the problem statement,

(20+x)/(25+x)=7/8

8*(20+x)=7*(25+x)

160+8x=175+7x

x=15

so the new number of boys is 20+x=35

and the new number of girls is 25+x=40

adding them , the group has total 75 members now.
