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.

The total number of male COVID–19 cases registered on Wednesday is what percent of the total number of male COVID–19 cases registered on Monday?

The correct answer is 80%.

From the given line graph, we can analyze the data for total registered COVID-19 cases (blue line) and female cases (orange line) on different days of the week:

1. Data for Monday:
Total cases registered on Monday = 800
Female cases registered on Monday = 300
Male cases registered on Monday = Total cases - Female cases

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

2. Data for Wednesday:
Total cases registered on Wednesday = 600
Female cases registered on Wednesday = 200
Male cases registered on Wednesday = Total cases - Female cases

$\text{Male cases (Wednesday)}=600-200=400$

3. Calculating the required percentage:
We need to find what percent the total number of male COVID-19 cases on Wednesday is of the total number of male COVID-19 cases on Monday.

$\text{Required Percentage}=\left(\frac{\text{Male cases on Wednesday}}{\text{Male cases on Monday}}\right)\times 100$

$\text{Required Percentage}=\left(\frac{400}{500}\right)\times 100=80\%$

Thus, the total number of male COVID–19 cases registered on Wednesday is 80% of the total number of male COVID–19 cases registered on Monday.
