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 average number of male COVID–19 cases registered on Monday, Tuesday and Friday?

The correct option is 400.

Let's analyze the data provided in the line graph:

The blue line represents the Total number of COVID–19 cases registered, and the orange line represents the Number of female COVID–19 cases registered.

From the image, the values on Monday, Tuesday, and Friday are as follows:

• Monday:
Total cases = 800
Female cases = 300
Male cases = Total cases - Female cases = 800 - 300 = 500

• Tuesday:
Total cases = 700
Female cases = 400
Male cases = Total cases - Female cases = 700 - 400 = 300

• Friday:
Total cases = 900
Female cases = 500
Male cases = Total cases - Female cases = 900 - 500 = 400

Now, we calculate the total number of male cases registered on Monday, Tuesday, and Friday combined:

$\text{Total Male Cases}=500+300+400=1200$

To find the average number of male COVID–19 cases on these three days, divide the total male cases by 3:

$\text{Average}=\frac{1200}{3}=400$

Thus, the average number of male COVID–19 cases registered on Monday, Tuesday, and Friday is 400.
