Question

The total number of women in the building is approximately what percent of the total number of members in the building?

• A. $45\%$
• B. $33\%$
• C. $42\%$
• D. $27\%$
• E. $38\%$

Answer 1

The correct option is E $38\%$

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 $=\frac{50}{80+50}\times 100=38\%$
