The Correct Option is C
Solution and Explanation
- The total number of executives across all companies is 10,000.
- The percentage distribution of employees across the companies is:
- \( C1: 15% \)
- \( C2: 5% \)
- \( C3: 8% \)
- \( C4: 32% \)
- \( C5: 20% \)
- \( C6: 20% \)
Step 1: Calculate the number of executives in each company
The number of executives in each company is:
- Number of executives in \( C1 = 15% \times 10,000 = 1500 \)
- Number of executives in \( C2 = 5% \times 10,000 = 500 \)
- Number of executives in \( C3 = 8% \times 10,000 = 800 \)
- Number of executives in \( C4 = 32% \times 10,000 = 3200 \)
- Number of executives in \( C5 = 20% \times 10,000 = 2000 \)
- Number of executives in \( C6 = 20% \times 10,000 = 2000 \)
Step 2: Calculate the number of management degree holders in \( C2 \) and \( C5 \) - For \( C2 \), the ratio of executives with a management degree is \( 1:4 \), meaning 1 out of every 5 executives has a management degree. \[ \text{Management degree holders in } C2 = \frac{1}{5} \times 500 = 100 \] - For \( C5 \), the ratio of executives with a management degree is \( 9:1 \), meaning 9 out of every 10 executives have a management degree. \[ \text{Management degree holders in } C5 = \frac{9}{10} \times 2000 = 1800 \] Step 3: Total management degree holders in \( C2 \) and \( C5 \) The total number of management degree holders in \( C2 \) and \( C5 \) together is: \[ 100 + 1800 = 1900 \] Thus, the total number of management degree holders in companies \( C2 \) and \( C5 \) is 1900, corresponding to Option (C).
Final Answer: (C) 1900
Top Questions on Ratio and Proportion
Health insurance plays a vital role in ensuring financial protection and access to quality healthcare. In India, however, the extent and nature of health insurance coverage vary significantly between urban and rural areas. While urban populations often have better access to organized insurance schemes, employer-provided coverage, and awareness about health policies, rural populations face challenges such as limited outreach of insurance schemes, inadequate infrastructure, and lower awareness levels. This urban-rural divide in health insurance coverage highlights the broader issue of healthcare inequality, making it essential to analyze the factors contributing to this gap and explore strategies for more inclusive health protection. A state-level health survey was conducted.
The survey covered 1,80,000 adults across urban and rural areas. Urban residents formed 55% of the sample (that is, 99,000 people) while rural residents made up 45% (that is, 81,000 people). In each area, coverage was classified under four heads – Public schemes, Private insurance, Employer-provided coverage, and Uninsured. In urban areas, Public coverage accounted for 28% of the urban population, Private for 22%, Employer for 18%, and the remaining 32% were Uninsured. In rural areas, where formal coverage is generally lower, Public coverage stood at 35%, Private at 10%, Employer at 8%, while 47% were Uninsured.
For this survey, “Insured” includes everyone covered by Public + Private + Employer schemes, and “Uninsured” indicates those with no coverage at all. Officials noted that public schemes remain the backbone of rural coverage, while employer and private plans are relatively more prevalent in urban centres. (250 words)
