Answer 1

The correct option is A 19:18

Number of boys in 7th and 9th together $=(\frac{8}{17}\times \frac{17}{100}+\frac{5}{9}\times \frac{16}{100})4500=760$
Number of girls in 5th and 6th together $=(\frac{5}{9}\times \frac{18}{100}+\frac{3}{8}\times \frac{16}{100})4500=720$
Reqd. ratio = 760:720 = 19:18
