Let, no. of boys in dance club be x and no. of boys in computer club be y
No. of girls in dance club = 2/5x
Total number of students in dance club = x + 2x/5 = 7x/5
6/7 of computer club students are girls
No. of boys in computer club = 1/7x (total students in computer club)
y = 1/7x (total students in computer club)
Total number of students in computer club = 7y
Total no. of students in dance club is half of that of computer club
7x/5 = 1/2 (7y)
=> y/2 = (7 * 2)/(5 * 7) = 2/5 = 2:5
The number of girls in the dance club was 2/5 the number of boys in it. The number of girls in the computer club was 6/7 the total number of students in it. The total number of students in the dance club was 1/2 the total number of students in the computer club. Find the ratio of the number of boys in the computer club to the number of boys in the dance club
