Question

In a housing society, 30% of residents are men over 18 and 40% are women over 18. If there are 24 children, how many total residents live in the society?

• A. 75
• B. 80
• C. 90
• D. 100
• E. 60

Hint:

Always sum the known percentages first to find the "remainder" percentage that represents the absolute number given in the question.

Answer 1

The Correct Option is B

Step 1: Analyse options.
- Percentage of adults (men + women) = $30\% + 40\% = 70\%$. - Percentage of children = $100\% - 70\% = 30\%$. - Given: $30\% \text{ of Total} = 24$. - Total = $\frac{24 \times 100}{30} = 80$.
Step 2: Conclusion.
There are 80 total residents. Final Answer: (b) 80
