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 Friday is what percent more than the total number of male COVID–19 cases registered on Tuesday?

The correct answer is $33\frac{1}{3}\%$.

Step 1: Understand the Data from the Line Graph

From the provided line graph, we can extract the following data for Total registered COVID-19 cases (represented by the blue line) and Female registered COVID-19 cases (represented by the orange line):

• Tuesday:
Total cases = 700
Female cases = 400

• Friday:
Total cases = 900
Female cases = 500

Step 2: Calculate the Number of Male COVID-19 Cases

The number of male cases is calculated as: Male cases = Total cases - Female cases

• Male cases registered on Tuesday:

$\text{Male cases (Tuesday)}=700-400=300$

• Male cases registered on Friday:

$\text{Male cases (Friday)}=900-500=400$

Step 3: Calculate the Percentage Increase

We need to find what percent the total number of male COVID-19 cases on Friday is more than that on Tuesday:

$\text{Difference in male cases}=400-300=100$

Now, calculate the percentage increase with respect to Tuesday's male cases:

$\text{Percentage increase}=\left(\frac{400-300}{300}\right)\times 100\%$

$\text{Percentage increase}=\frac{100}{300}\times 100\%=\frac{100}{3}\%=33\frac{1}{3}\%$

Thus, the total number of male COVID–19 cases registered on Friday is $33\frac{1}{3}\%$ more than on Tuesday.
