• E. 39

Answer 1

The correct option is D 34

Number of boys in standards 6th and 7th $=((\frac{5}{8}\times \frac{16}{100})+(\frac{8}{17}\times \frac{17}{100}))\times 4500=810$
Total number of boys in the school $((\frac{4}{9}\times \frac{18}{100})+(\frac{5}{8}\times \frac{16}{100})+(\frac{8}{17}\times \frac{17}{100})+(\frac{3}{5}\times \frac{18}{100})+(\frac{5}{9}\times \frac{16}{100})+(\frac{7}{15}\times \frac{15}{100}))\times 4500=2371$
Reqd. percentage $=\frac{810}{2371}\times 100=34.16\simeq 34\%$
