Line graph given below shows the total number of ‘COVID–19’ cases registered in AIIMS Delhi on five different days and the number of females ‘COVID-19’ cases out of total registered cases in these five days. Read the data carefully and answer the questions.

Find the ratio of the total number of female COVID –19 cases registered on Wednesday to the total number of male COVID–19 cases registered on Monday respectively?

The correct option is 2 : 5.

Let's analyze the given line graph to extract the required data for Monday and Wednesday:

1. Data for Monday:

Total COVID-19 cases registered (blue line) = 800
Number of female COVID-19 cases registered (orange line) = 300

To find the number of male COVID-19 cases registered on Monday:

$\text{Male cases (Monday)}=\text{Total cases}-\text{Female cases}$

$\text{Male cases (Monday)}=800-300=500$

2. Data for Wednesday:

Number of female COVID-19 cases registered on Wednesday (orange line) = 200

3. Calculate the required ratio:

We need to find the ratio of female cases on Wednesday to male cases on Monday:

$\text{Ratio}=\frac{\text{Female cases on Wednesday}}{\text{Male cases on Monday}}$

$\text{Ratio}=\frac{200}{500}=\frac{2}{5}$

Thus, the required ratio is 2 : 5.
