• C. 244
• D. 246
• E. 252

Answer 1

The correct option is A 242

Total number of boys $=((\frac{4}{9}\times \frac{18}{100})+(\frac{5}{8}\times \frac{16}{100})+(\frac{8}{17}\times \frac{17}{100})+(\frac{3}{5}\times \frac{18}{100})+(\frac{5}{9}\times \frac{16}{100})+(\frac{7}{15}\times \frac{15}{100}))\times 4500=2371$
Total number of girls = 4500-2371 = 2129
Reqd. Difference = 2371-2129 = 242
