There were 5 more members in the Choir than in the Robotics Club. There were 32 girls in the Choir Club and 19 girls in the Robotics Club. The number of boys in the Choir Club was 5/7 the number of boys in the Robotics Club. How many members were there in Choir Club?
Let Cg = number of girls in Choir club; Cb = number of boys in Choir club
Rg = number of girls in Robotics club; Rb = number of boys in Robotics club
We are told
Cg = 32
Rg = 19
Cb = Rb*5/7
Cg + Cb = Rg + Rb + 5
Can you take it from here?
