Read the following passage and answer the questions that follow:

The following table - I shows the percentage (%) distribution of patients of various diseases in the world and table - II shows the percentage (%) distribution of all the patients and Kidney patients in various continents, namely, Europe, Australia, South America, Africa, North America and Asia in the year 2023. Total population of the world in the year 2023 is 800 crore and 10% of them are patients. Based on the data in the tables, answer the questions that follow.

Table - I:

 Disease wise Percentage of Patients in the world.
​

Table II: Continent - wise Details of all Patients and Kidney patients.

If the number of patients increases by 10% every year in Europe, then what is the difference between the number of patients in Europe after two years and the number of Kidney patients in South America in 2023?

Correct option is A

Total population in the world = 800 crore
Total patient in the world = 10% of 800 = 80,0000000
Patient in Europe = 10% of 80,0000000 = 80000000
Increased patient in Europe after two years = 110/100 × 110/100 × 80000000 = 96800000
Number of kidney patient in South America in 2023 = 30% ×40% of 800000000 = 96000000
Difference between the number of patients in Europe after two years and the number of Kidney patients in South America in 2023 = 96800000 - 96000000 = 800000 = 8 lakh
