Question

There is a list of a hospital with admitted patients by age for one day. There were 1000 patients attended. Among these patients, children below 5 years were 600; 200 were between the age of 5 years and 45 years and 200 were above 45 years. Then the proportion of patients attended by the hospital to be of age less than five years and adults of 45 years and above is

• A. \(0.60\)
• B. \(0.20\)
• C. \(0.80\)
• D. \(0.40\)

Hint:

Proportion: \[ \frac{\text{Part}}{\text{Whole}} \] Percentage can be obtained by multiplying the proportion by \(100\).

Answer 1

The Correct Option is C

Concept: Proportion is defined as: \[ \text{Proportion} = \frac{\text{Number of favourable cases}} {\text{Total number of cases}} \]

Step 1: Identify the required categories.
Children below 5 years: \[ 600 \] Adults aged 45 years and above: \[ 200 \]

Step 2: Find the total favourable patients.
\[ 600+200 = 800 \] Thus, \[ \text{Required patients}=800 \]

Step 3: Find the total number of patients.
Given: \[ 1000 \] patients attended the hospital.

Step 4: Calculate the proportion.
\[ \text{Proportion} = \frac{800}{1000} \] \[ =0.8 \]

Step 5: Write the final answer.
\[ \boxed{0.80} \] Hence option (C) is correct.
