• B. 40%
• C. 45%
• D. 35%
• E. 55%

Answer 1

The correct option is C 45%

Total number of girls $\left[(\frac{4}{9}\times \frac{20}{100})(\frac{3}{10}\times \frac{30}{100})(\frac{3}{5}\times \frac{25}{100})(\frac{5}{8}\times \frac{12}{100})(\frac{1}{3}\times \frac{13}{100})\right]\times 1800=805$
Reqd. percentage $=\frac{805}{1800}=44.72\%\simeq 45\%$
