• B. 83.45%
• C. 81.25%
• D. 72.15%
• E. None of these

Answer 1

The correct option is C 81.25%

Number of men in the building $=80$
Number of women $=\frac{80\times 62.5}{100}=50$
Men who learn to dance $=8$
Women who learn to sing $=\frac{50\times 24}{100}=12$
Women who watch movies $=50\times \frac{1}{5}=10$
Men who match movies $=\frac{13}{2}\times 10=65$
Men who learn to sing $=80-65-8=7$
Women who learn to dance $=50-10-12=28$
Required percentage $=\frac{65}{80}\times 100=81.25\%$
